[00:37:35] <Sedrik> Hi.  I'm a Postfix (mail server) n00b looking for some help.  I have a multi-server web cluster than needs to send mail.  Incoming mail to the domain goes to a completely different host (gmail).  MX records are pointing to Gmail.  Currently I have Postfix setup on one of the boxes in the web cluster and the other boxes connect to it to send their mail.  All mail currently ends up in spam...
[00:37:37] <Sedrik> ...folders.  I have SPF records created.
[00:37:56] <Sedrik> I'm trying to determine what the optimal setup for this kind of environment is

[01:07:31] <Motoko-chan> Do you know the cause of the problem?
[01:07:39] <Motoko-chan> Like why it's ending up in there.
[01:08:02] <Motoko-chan> Also, disable SPF for now (it's almost worthless anyway) to eliminate it from the situation.
[01:14:22] *** Azrael has joined #postfix
[01:14:25] <Nodlehs> Any common noob mistake that results in postfix not using virtual_mailbox_domains? It looks at my other virtual settings to validate users, but not domains
[01:15:09] <Azrael> does anyone have recommendations of how to block "spear phishing" attacks on our MX's?
[01:15:16] <Azrael> we're getting targeted phish
[01:17:47] <Sedrik> Motoko-chan: Sorry, was away.  No I don't really know the cause of the problem.
[01:18:03] <Motoko-chan> What spam folders the items?
[01:18:10] <Sedrik> gmail
[01:18:12] <Motoko-chan> Specific site, or just in general?
[01:18:14] <Motoko-chan> Ah.
[01:18:19] <Motoko-chan> Bug Google?
[01:18:42] <Motoko-chan> Also, check your outbound IPs for presence on any blocklists.
[01:18:45] <Motoko-chan> openrbl.org
[01:19:11] <Motoko-chan> Then also make sure the outbound have a proper PTR in DNS that matches an A record for them.
[01:21:28] <Sedrik> Ya, I had my ISP set up the PTR record.  My hunch is that it's because i have servers 2 thru 6 sending mail thru server 1, and that that's all communicated on a private network.  gmail shows that the mail originated from 10.x.x.x.
[01:21:47] <Sedrik> but that's more of an observation than anything else.
[01:22:01] <Motoko-chan> That shouldn't be an issue.
[01:22:12] <Motoko-chan> It's the one that touches the cloud you need to worry about.
[01:22:22] <Motoko-chan> Also make sure you only have *one* PTR for the IP.
[01:22:33] <Sedrik> Received: from myhost-web4 (unknown [10.248.0.13])
[01:22:37] <Sedrik> is what google shows
[01:22:39] <Motoko-chan> Many things don't like multiple PTR records and see issues.
[01:22:54] <Motoko-chan> That's actually inserted by the next server up, not Google.
[01:23:16] *** gpled has joined #postfix
[01:23:30] <Sedrik> ya -- the next server up is my first web server -- the one with postfix on it:  by smtp.myhost.com (Postfix)
[01:23:47] <Sedrik> 'myhost' is not the real address there
[01:24:01] <Motoko-chan> Anyway, check DNS.
[01:24:03] <Sedrik> and smtp.myhost.com resolves to the server sending the mail
[01:24:10] <Motoko-chan> It's the most common problem.
[01:25:13] <Motoko-chan> If your server gives a helo of "smtp.example.com" then the PTR for the IP it sends from should be the same.
[01:25:20] <Motoko-chan> If it is different, it can cause problems.
[01:25:56] <Sedrik> is there anyway for me to query for the PTR?  my ISP assured me they set it up, but they've been wrong before ;)
[01:26:34] <jduggan> dig -x
[01:26:54] <jduggan> host -t PTR ip (in-addr.arpa format)
[01:28:31] <Motoko-chan> dig -x works nicely
[01:28:39] <Motoko-chan> And will show if there are multiple records.
[01:28:44] <Motoko-chan> nslookup and host don't iirc
[01:29:04] <Sedrik> dig -x IP_ADDR   or dig -x SMTP_HOST?
[01:29:14] <Motoko-chan> dig -x IP
[01:29:32] <Sedrik> ah
[01:29:34] <Sedrik> yes
[01:29:37] <Sedrik> just 1 IP it looks likke
[01:29:39] <Sedrik> like
[01:29:52] <Motoko-chan> Does it match the HELO of the server?
[01:30:37] <Sedrik> yes, it does
[01:31:27] <Sedrik> should the HELO respond with the ending period?  the PTR record has a period have the '.com'
[01:32:47] <Motoko-chan> No, it shouldn't.
[01:32:57] <Motoko-chan> That's a DNS system thing.
[01:33:00] <Sedrik> ok
[01:33:29] <rob0> smtp.myhost.com. ? NXDOMAIN for me.

[08:08:01] <pepe_swash> hello. how do i prevent tls for pop?
[08:09:12] <pepe_swash> i read everywhere how to do that for smtp, but i don't use the smtp part of postfix.
[08:09:50] <pepe_swash> and i've disables tls for smtp anyway. i still get cert errors when i read account using thiunderbird
[08:10:43] <Motoko-chan> Make sure to choose "No" for encryption.
[08:10:49] <Motoko-chan> Default is "if available"
[08:11:44] <pepe_swash> if i do that i get an error "plaintext auth disallowed on non-secure connections"
[08:12:09] <pepe_swash> which is why i thought postfix was the culprit
[08:12:17] <pepe_swash> and had encryption enabled
[08:12:30] *** phnord has joined #postfix
[08:22:11] <rob0> Um, Pepe, there IS no "pop part" of Postfix. That would be some other server.

[12:33:52] <shasta> ams, files in maildir are named with a unix timestamp, you can split maildirs "by date"
[12:33:57] <ams> or maybe zfs is nicer than ext3 on lots of files
[12:34:15] <ams> shasta: uhm,no i cannot
[12:34:23] <ams> that would screw up whatever silly rules a user has
[12:34:36] <shasta> well, just for backups, that is
[12:34:54] <ams> and how on earth would that be useful?
[12:35:07] <ams> i still would have to traverse 100k files per user, which is the bottleneck
[12:35:18] <Trengo> do a FS snapshot
[12:35:46] <ams> does ext3 support them?
[12:35:49] <shasta> no
[12:35:55] <shasta> LVM does, tho
[12:36:52] <ams> mm...
[12:36:57] * ams rtfms a bit more
[12:37:28] <Trengo> yeah and wouldn't disrupt service or setup much
[12:37:47] <shasta> (man lvcreate, see -s)
[12:37:56] <ams> can one dump snapshots to some offsite box and restore?
[12:38:21] *** cpm has joined #postfix
[12:40:21] <shasta> well, lvm snapshot is a "frozen image" of the snapshotted volume
[12:40:43] <jelly> ams: our mailbox folders are split on multiple filesystems, each around 100GB size
[12:40:48] <shasta> you can backup it just like an actual filesystem with whatever tools you ues
[12:40:55] <shasta> s/ues/use/
[12:44:45] <f3ew_> ams, get a netapp?
[12:47:12] <ams> i think ih ave a plan now, thanks guys

[12:55:31] <zeroC> hi there...
[12:55:35] <rgoldber> hi all - I just warpped up a 5 hour emergency migration of 9000 accts, 400 domains from qmail + ldap + custom userprefs app -> postfix + mysql
[12:55:53] <rgoldber> it sucked, I'm not an email admin, I'm more of a net admin.  it sucked.
[12:56:11] <zeroC> anyone german here?
[12:57:30] <rgoldber> anyway, one quick question.  passwords are in plaintext in the db - I need smtp auth to work - with the passwd in plaintext, am I going to be able to enable md5 or cram in a straightforward manner?
[12:58:19] <shasta> rgoldber, cram-md5 and digest-md5 can work *only* if you have plaintext password at the server end
[12:58:26] <shasta> (well, to be precise, at both ends :>)
[12:59:49] <rgoldber> ah ha.  well goody.
[13:00:26] <rgoldber> lemme poke around for a moment then
[13:00:57] * cpm uses plain auth, encrypted passwords in the database, and forces tls to avoid passing in the clear. done.
[13:01:39] <rgoldber> I have to accomodate the setting on hundreds of computers..
[13:02:12] <rgoldber> none of this was by choice, btw - I've been up since 1am.  it's 6am here now
[13:04:23] <f3ew_> rgoldber, ouch
[13:04:38] <f3ew_> 1 am is too early to be asleep
[13:04:58] <zeroC> i will try... ;) i've uploaded my postconf -n on http://pastebin.com/f6183076a
[13:05:19] <rgoldber> gracias zeroC
[13:05:38] *** denis_ has quit IRC
[13:05:46] <zeroC> ups, please not in spanish... ;)
[13:05:53] <zeroC> english is hard enough
[13:06:07] <zeroC> so but, i cannot send any mail out... i've deleted my mail.log...
[13:06:15] <zeroC> still wait, i will add a new one
[13:06:16] <zeroC> :)
[13:06:32] <zeroC> but the problem is, no mail comes out
[13:08:01] <zeroC> does anyone now, what i can do, to get a new mail.log?
[13:08:14] 
[13:08:17] <zeroC> its archlinux
[13:09:38] <mwalling> syslogd should create a new file when it is restarted
[13:10:29] <zeroC> i've restart it, but nothing happened
[13:11:07] <zeroC> mwalling: sry
[13:11:10] <zeroC> it works
[13:11:10] <zeroC> :D
[13:12:21] <zeroC> mail.log http://pastebin.com/f37b2837
[13:16:18] <zeroC> mwalling: with it works i meant the mail.log was created

[13:33:09] <zeroC> :)
[13:33:09] <zeroC> sry
[13:46:02] <rgoldber> ok - so, postfix - sasl - pam - mysql, they're talking to eachother and I can use use PLAIN and LOGIN.  I can add  DIGEST-MD5 and CRAM-MD5 to my mech_list, and the the smtpd claims to support it, but of course authentication doesn't work.  I feel I'm missing jut one key thing here.  Any takers?
[13:49:16] <mwalling> !sasl
[13:49:16] <knoba> mwalling: "sasl" : SASL is 'Simple Authentication and Security Layer', necessary for SMTP AUTH, and provided to Postfix by addin software. Cyrus SASL and/or Dovecot IMAP/POP3 can provide SASL. See http://www.postfix.org/SASL_README.html for details.
[13:49:49] <zeroC> mwalling: do you have an idea for my problem too?
[13:49:55] <mwalling> also, you said you werent a mail admin, but i'm sure you learned something in the past 6 hours, but you should still read
[13:49:59] <mwalling> !basic
[13:50:00] <knoba> mwalling: "basic" : http://www.postfix.org/BASIC_CONFIGURATION_README.html : a good starting place for Postfix beginners, many common questions are answered here.
[13:50:03] <mwalling> and
[13:50:06] <mwalling> !standard
[13:50:06] <knoba> mwalling: "standard" : Your question is probably answered in http://www.postfix.org/STANDARD_CONFIGURATION_README.html
[13:50:17] <_apk> hi! :)
[13:50:39] <zeroC> hi _apk
[13:50:41] <mwalling> and /topic
[13:50:42] <mwalling> er
[13:50:59] <rgoldber> I'll keep it up, just getting sleepy/stupid
[13:51:23] <rgoldber> (but yeah, I've read that)
[13:51:29] <mwalling> and
[13:51:31] <mwalling> !virtual
[13:51:31] <knoba> mwalling: "virtual" : a way to configure additional domains and user accounts (that do not need to exist in your /etc/passwd). See: http://www.postfix.org/VIRTUAL_README.html
[13:54:13] <shasta> rgoldber, what do you mean by "smtpd claims to support it"?
[13:54:53] <rgoldber> I mean if I add trhose to mech_list and do an ehlo, it responds with them in the list
[13:55:12] <rgoldber> but, if I try and auth with either of them, it does not work.
[13:55:29] <rgoldber> (but PLAIN and LOGIN do)
[13:58:21] <rgoldber> so, postfix is talking to sasl is talking to pam is talking to mysql
[14:08:07] <rgoldber> got packt capture, transaction looks ok, but of course I get 535 auth failed back

[16:41:21] *** UQlev has joined #postfix
[16:41:21] <ams> (mail/news spool)
[16:41:27] <seekwill> We use ext2
[16:42:18] <ams> interesting
[16:42:23] <f3ew_> ReiserFS, but it's unreliable under load
[16:42:27] <ams> not xfs or some such beast?
[16:43:03] <seekwill> Is it cliche to make jokes about ReiserFS?
[16:43:13] <f3ew_> yes
[16:43:23] <f3ew_> xfs, not for mail spools
[16:43:31] <f3ew_> ufs2 is good
[16:43:35] <f3ew_> as is ZFS
[16:43:37] <seekwill> ams: ext2 comes with RHEL... so just "easier"
[16:43:45] <ams> i don't use rhel...
[16:43:46] <f3ew_> ext2 is good too
[16:43:51] <f3ew_> What do you use?
[16:43:55] <ams> debian
[16:44:02] <seekwill> We've had issues with zfs. ufs seemed better, but I forgot the options.
[16:44:05] <ams> in either case, not relevant...
[16:44:10] <jelly> seekwill: rhel doesn't really support a whole bunch of filesystems... you have ext3 or ext2.
[16:44:22] <seekwill> jelly: That's the point
[16:44:43] *** deemon is now known as dh
[16:44:48] <ams> so nobody uses a journal fs for spools?
[16:45:03] * jelly uses ext3 by default
[16:45:12] <f3ew_> jelly, also XFS
[16:45:20] <jelly> f3ew_: since when?
[16:45:26] <f3ew_> Ancient times
[16:45:40] *** dh is now known as deemon
[16:45:42] <f3ew_> you just have to load the module at boot if you want the rootfs to be on xfs
[16:46:06] <ams> so do you pass any funny switches to the kernel for ext2/3?
[16:46:08] <jelly> f3ew_: my rhel4 kernel doesn't even have an xfs module
[16:46:12] <ams> say, noatime and such.
[16:46:22] <seekwill> ams: noatime is good
[16:46:45] <jelly> f3ew_: a rhel5 machine neither
[16:47:19] <ams> well then, i'll go with ext3 as I did before...
[16:47:29] <f3ew_> hmmmm
[16:47:37] <jelly> f3ew_: mmm, scrap that last one, I forgot I reinstalled the '5 machine back to rhel4
[16:49:43] <jelly> seekwill: noatime messes up etrn, afair?
[16:50:10] <f3ew_> yes
[16:50:24] <f3ew_> but this is spool, not queue
[16:50:40] *** rgoldber has quit IRC
[16:51:43] <jelly> oh, right
[16:51:54] * jelly doesn't read O:-)
[16:52:53] <ams> any other useful switches for a mailspool?
[16:53:37] <jelly> ext3 with hashed directory entries (-O dir_index; might or might not be the default for your mke2fs, depending on version and config) is a-ok
[16:54:22] <ams> interesting
[16:55:00] <ams> anything else fun? :)
[16:55:51] <jelly> this was one of two killer features reiserfs v3 had, compared to ext2 at that time.  The other one was tail packing
[16:56:51] <jelly> however, after waiting for one reiserfsck run to finish under 72 hours, we somehow decided against using reiserfs ever again
[16:58:51] <jelly> ams: not related to mail spool usage; but if you have dynamically expandable block devices (lvm or LUNs exported from a SAN device), using -O resize_inode will make your ext3 resizable online (no need to umount)
[16:59:25] <ams> ah, lovley
[17:01:19] <jelly> so basically mke2fs -j -O dir_index,sparse_super,resize_inode /dev/wherever; add labels and other options to taste
[17:11:17] <ams> and now for a stupid question...
[17:12:00] <ams> what are the silly options to setup so that mail is dumped to /com/mail/USER, /com/mail/USER being the root directory (i.e. /home/USER/Maildir)?

[22:58:23] <dennda> Hi. In virtual_domains, can I create an alias that fetches all mail being sent to it and forwards them to another email adress on a completely different server?

[22:59:40] *** madrescher has quit IRC
[23:00:15] *** madrescher has joined #postfix
[23:02:33] <dennda> Ah very well. It works by just putting the email adress behind the alias :)

[23:14:26] *** Draecos has joined #postfix
[23:17:17] *** UberDuper has joined #postfix
[23:18:16] <UberDuper> So I have an interesting mail setup and I'm trying to figure a way to tackle backscatter and queuing of NDRs that'll never go anywhere anyhow.
[23:18:43] *** _zsh has quit IRC
[23:18:44] *** madrescher has quit IRC
[23:18:47] <UberDuper> I've got a postfix/mailscanner smtp gateway that relays to a postfix/cyrus mailhost.
[23:19:59] <UberDuper> On the mailhost we use a virtusertable as an alias file. In many cases we have an entry @domain.tld  user at domain dot tld
[23:20:07] <UberDuper> As a catch all for the domain.
[23:20:41] <UberDuper> And we have entries for commonlyspammed at domain dot tld   nosuchaddress
[23:20:53] *** keffer has quit IRC
[23:20:56] <UberDuper> nosuchaddress is defined in the aliases db to deliver to /dev/null
[23:21:53] <UberDuper> Domains configured in this manner aren't a problem since all addresses at those domains are valid and get delivered.
[23:22:13] <UberDuper> It's the domains that don't use the @domain.tld  user at domain dot tld virtusertable entry.
[23:22:45] <UberDuper> We're generating and attempting to deliver tons of NDRs.
[23:28:20] *** madduck has joined #postfix
[23:28:28] <madduck> okay, this is freaking me out a bit:
[23:28:28] <madduck> Jul 16 23:28:14 seamus postfix/pipe[20927]: 3537E401C23: to=<testlist at lists dot madduck.net>, relay=mailman, delay=1.5, delays=0.8/0.01/0/0.65, dsn=2.0.0, status=sent (delivered via mailman service)
[23:28:40] <madduck> but /etc/mailman/postfix-to-mailman.py isn't accessed
[23:28:52] <madduck> /dev/sda5 on / type xfs (rw,noatime)
[23:29:01] <madduck> aha, that explains this part
[23:29:08] <madduck> still,mailman doesn't get the message.
[23:29:17] *** pickcoder has joined #postfix
[23:29:19] <madduck> *nothing* in its logs
[23:30:25] <xpoint> madduck, what version of mailman ?
[23:30:46] <madduck> 2.1.11
[23:31:08] *** c0m has joined #postfix
[23:31:33] <xpoint> try reconfigure without postfix-to-mailman.py and use the old style with alias pipes
[23:31:51] <madduck> is it a known bug?
[23:32:07] <xpoint> could be i run 2.1.9 here
[23:32:07] <madduck> i'd really rather not go via alias pipes... we have >1000 lists
[23:32:35] <xpoint> ups
[23:33:11] <xpoint> it can be postfix that miss transport_maps to mailman:
[23:33:37] <xpoint> but the logs above show this works
[23:34:03] <xpoint> reley=mailman, so the mails is lost in the py code
[23:34:34] <madduck> ./conf/mailman_lists.hash:testlist at lists dot madduck.net      mailman:
[23:34:37] <madduck> and so on...
[23:34:47] <madduck> yeah, looks like it.
[23:35:01] <madduck> ./main.cf:#mailman_destination_recipient_limit = 1
[23:35:03] <madduck> hm...
[23:35:06] <madduck> wtf?
[23:35:26] <madduck> someone has been playing around
[23:35:34] *** Joe_Wulf has joined #postfix
[23:35:40] <xpoint> ./main.cf:#mailman_destination_recipient_limit = 1 vs ./main.cf:mailman_destination_recipient_limit = 1
[23:35:52] <madduck> yeah
[23:36:14] <xpoint> # remove if its commented
[23:36:55] <markl__> is it possible for my test null mail server to accept mail for all domains
[23:37:02] <markl__> e.g. mydestination *
[23:37:41] <xpoint> sendmail -bv <>
[23:37:57] *** havvg has quit IRC
[23:38:00] <xpoint> not tested here )
[23:38:04] <madduck> if only i knew where the python script's stderr went to
[23:38:35] <xpoint> madduck, yes, make a good bug report on it
[23:39:33] <madduck> once i have more info
[23:39:56] <madduck>     sys.exit(EX_SOFTWARE)
[23:39:57] <xpoint> madduck, it took me very long time to make mailman work here a lack of docs and wroung info makes it hard to do right
[23:40:10] <madduck> in the .py file still causes the mail to be accepted
[23:40:54] <madduck> oh lol, don't use sudoedit :)
[23:41:03] <madduck> Jul 16 23:40:59 seamus postfix/pipe[25453]: E5B38401C1C: to=<testlist at lists dot madduck.net>, relay=mailman, delay=0.37, delays=0.27/0.01/0/0.09, dsn=5.3.0, status=bounced (internal software error. Command output: FOOBAR)
[23:41:07] <madduck> :)
[23:41:27] <xpoint> fixed ?

[23:45:01] *** JoeWulf has quit IRC
[23:48:55] <xpoint> hmm
[23:49:42] <xpoint> args to mailman is maybe wroing from the master.cf pipe
[23:50:01] <madduck> nope
[23:50:03] <xpoint> hmm hmm
[23:50:05] <madduck> (and it used to work)
[23:50:30] <madduck> i have to poke more in the mailman inards
[23:50:43] <xpoint> yes
[23:52:12] *** j_s has quit IRC
[23:52:16] <madduck> Group mismatch error.  Mailman expected the mail
[23:52:16] <madduck> wrapper script to be executed as group "daemon", but
[23:52:16] <madduck> the system's mail server executed the mail script as
[23:52:16] <madduck> group "madduck".  Try tweaking the mail server to run the
[23:52:28] <madduck> so in this case, it's being executed as group daemon
[23:52:31] <madduck> uh, list
[23:53:04] * madduck tries user=list:daemon instead of user=list
[23:53:13] <madduck> no luck
