If a bad actor has a bot connecting this thread with pastes, everything will be copied?[17:59:23] <samgoody> But, OK, will use the real IP/Address. It is the only thing I changed.[17:59:34] <KaiForce> If lunaphytes concern is valid, use an unregistered domain name[17:59:38] <lunaphyte> there may be an arguable benefit to withholding one's own domain name. however, it is not ok to then use some other person's domain name in its place. that's the point[17:59:52] <lunaphyte> !tell samgoody example[17:59:52] <knoba> samgoody: "example" : Example.TLD has been reserved for examples in generic top-level domains (com,net,org) and many other TLDs.

But point taken, and thank you for correcting me.[18:00:31] *** bolt has joined #postfix[18:00:41] <KaiForce> lunaphyte: why not?[18:01:06] <KaiForce> use an unregistered domain, identify it as such. Not rude in any way.[18:01:28] <lunaphyte> samgoody: no worries, thank you for being receptive to the critique[18:01:50] <lunaphyte> KaiForce: there is no need to. use your domain name, or use a domain name specifically established for use in examples[18:03:44] <samgoody> Here's the output of the error log: http://pastebin.ca/3315020[18:04:30] <samgoody> And I already posted the link to the postconf, but here it i again. http://pastebin.ca/3314947[18:05:43] <samgoody> !relevant_logs[18:05:44] <knoba> samgoody: "relevant_logs" : Relevant logs are mail.* syslog Postfix logs (NOT verbose, see !verbose) which show the entire handling of a single mail which illustrates the issue with which you want help. Random selections from your mail log might not do. IMAP/POP3 daemons and external delivery agents typically log to the same facility (mail); those are usually not relevant here.[18:05:45] <lunaphyte> yes, as you said, you're using reject_unknown_reverse_client_hostname, so if a mail server connects which cannot satisfy that restriction, the attempt will be rejected.[18:05:57] <lunaphyte> so normal behavior, in other words, so far.[18:06:18] <lunaphyte> some folks consider use of reject_unknown_reverse_client_hostname to carry too much collateral damage though, as you can probably see[18:07:22] <samgoody> I have a computer, let us say the ip is 1.2.3.4. I connect to a computer with postfix, on ip address 4.3.2.1. Which is the machine that has to meet the said restriction?[18:07:44] <lunaphyte> you also can't use other people's ip addresses in your examples ;)[18:08:13] <samgoody> are you being serious? what's the example IP I can use?[18:08:14] <lunaphyte> see rfc 5737 - use 192.0.2.0/24[18:08:57] <samgoody> excellent. OK. That is - Apple Mail (the MTA, right?) is at 192.0.2.0, and Postfix is at 192.0.2.1[18:09:08] <samgoody> which is the one that nees to resolve in both directions?[18:09:17] <lunaphyte> apple mail? as in mail.app?[18:09:21] <lunaphyte> postfix is the mta[18:09:36] <lunaphyte> mail.app is not a server. it's a client [and mua][18:09:42] <lunaphyte> *an mua[18:09:49] <samgoody> Yes, as in the mail app the MUA. sorry[18:09:55] <lunaphyte> mail.app is what is connecting to postfix?[18:10:00] <samgoody> Yes[18:10:01] <lunaphyte> that's your problem then.[18:10:19] <samgoody> I have mail-stack-delivery setup, which is Dovecot+Postfix[18:10:22] <lunaphyte> clients are not to connect to port 25. clients are to use the submission protocol [port 587][18:10:35] <lunaphyte> port 25 is only for servers to talk to other servers[18:11:08] <samgoody> In Apple mail, I set it to use port 587.[18:11:28] <lunaphyte> in your case, you do not have any overrides for the submission service[18:11:36] <samgoody> And everything works - both incoming and outgoing - when I remove that restriction of reject_unknown_reverse_client_hostname[18:11:43] <lunaphyte> so the submission service is using the global settings from main.cf[18:12:28] <lunaphyte> all of the smtpd_*_restrictions need to be explicitely set for the submission service in master.cf[18:13:03] <lunaphyte> master.cf includes a starting point for some of these, in the form of commented examples for the submission service[18:13:14] <KaiForce> samgoody: your IP address is what is failing on reverse, not the DNS name.[18:13:25] <lunaphyte> KaiForce: we're past that[18:14:20] *** TyrfingMjolnir has quit IRC[18:15:35] <samgoody> "Your IP addresss" meaning the IP address of the MUA. And it is failing, because submission should not have the restriction of reject_unknown_reverse_client_hostname since obviously the MUA cannot meet that. But since it inherits from main.cf it has the restriction, and fails.[18:15:42] <samgoody> Did I understand correctly?[18:16:25] <lunaphyte> correct[18:17:06] <lunaphyte> restrictions for smtp/mx traffic and for mua/client traffic are completely different, and thus need completely different settings in the postfix config[18:18:09] <lunaphyte> additionally, as a sort of side effect of that, you currently have smtp auth globally enabled in your config, which is a huge no no[18:18:42] <lunaphyte> mail servers talk to mtas, but mail clients [muas] talk to msas[18:19:55] <samgoody> What is msas?[18:20:29] <lunaphyte> !tell samgoody msa[18:20:29] <knoba> samgoody: "msa" : Message Submission Agent : a process which accepts message submissions from MUAs on port 587 known as 'message submission service' using the 'message submission protocol' defined by rfc4409. To enable message submission service in postfix uncomment the relevant lines in master.cf. also see !submission.[18:20:52] <samgoody> Also, once I uncomment any default option, it will immediately not inherit anything? Or do I have to overide whatever I dont want it to inherit?[18:21:03] <samgoody> Thank you very much for your patience.[18:21:27] <lunaphyte> start by uncommenting the rest of the submission service. then prepare a new !showconfig pastebin[18:21:32] <lunaphyte> we can continue from there[18:27:00] *** [NoClan]GoAway has quit IRC[18:27:45] <samgoody> http://pastebin.ca/3315137[18:28:37] <lunaphyte> looks better. now remove the submission specific bits from the global config[18:28:39] *** Lencl has quit IRC[18:29:01] <lunaphyte> permit_mynetworks, permit_sasl_authenticated both removed from main.cf[18:29:35] <lunaphyte> also combine helo and recipient restrictions into recipient restrictions, the global config[18:29:46] <lunaphyte> remove smtpd_sasl_auth_enable = yes from the global config[18:30:16] <lunaphyte> remove smtpd_tls_ask_ccert = yes, smtpd_use_tls = yes[18:30:24] *** Haudegen has quit IRC[18:30:51] <lunaphyte> oh, smtpd_sender_restrictions also getms moved in to recipient restrictions[18:31:02] <lunaphyte> remove broken_sasl_auth_clients = yes[18:31:52] <lunaphyte> you also have duplicates of defaults in your config. remove those[18:31:58] <lunaphyte> !tell samgoody duplicates[18:31:58] <knoba> samgoody: "duplicates" : the following can be used to list redundant settings defined in main.cf: (postconf -d; postconf -n) | sort | uniq -d - also see !compare[18:33:05] *** rsx has joined #postfix[18:33:18] <lunaphyte> reject_non_fqdn_sender, reject_non_fqdn_recipient, reject_unknown_sender_domain, reject_unknown_recipient_domain should be first in your restrictions, and should also be included in your submission restrictions[18:33:30] <samgoody> remove smtpd_helo_required = yes?[18:33:44] <lunaphyte> no[18:34:41] <lunaphyte> mailbox_size_limit = 0 is a huge no no. remove that[18:35:09] <lunaphyte> remove smtp_use_tls = yes[18:35:14] <samgoody> in the submission sender_restrictions?[18:35:43] <lunaphyte> put everything in recipient restrictions. no need for anything in the other restrictions[18:37:03] <samgoody> even reject_unknown_sender_domain, reject_sender_login_mismatch in main.cf?[18:37:50] <lunaphyte> yes[18:38:08] *** TyrfingMjolnir has joined #postfix[18:38:12] <samgoody> Hmm, will have to spend a while after this reading everything slowly and understanding each of the rules.

It only shows up in one place that I see?[18:44:48] <samgoody> Should I delete it anyway?[18:45:26] <lunaphyte> it's a duplicate in the sense that it just repeats the default which already exists[18:45:29] *** Haudegen has joined #postfix[18:46:04] <lunaphyte> not exists in the file. exists in the software itself.[18:48:39] <KaiForce> I ran through a test upgrade (Ubuntu 10.04 => 12.04 => 14.04) and it logged where I had dups at some stage[18:49:41] <samgoody> great.

Do you suggest it be removed?[20:28:48] <lunaphyte> at least arch has it. that's good[20:29:23] <lunaphyte> if you're not using the local or virtual mailbox classes, there are a number of settings not needed, in both main.cf and master.cf[20:34:39] <samgoody> we use postgre to store the domains, users, and aliases. mails are stored in directories based on the domain/user. Doesn't that use the virtual class?[20:36:43] <samgoody> (And then dovecot uses the path to get the user's name)[20:37:12] <lunaphyte> no[20:37:30] <lunaphyte> those details are immaterial[20:38:41] <lunaphyte> what matters is what mda you have selected to use for mail delivery[20:38:56] <samgoody> I must admit to finding the postfix settings a little bit counter-intuitive sometimes ;-/[20:39:07] <lunaphyte> if you've selected local(8), provided by postfix, then you use the local domain class, and thus mydestination[20:39:09] <samgoody> Which is the virtual and local settings that aren't needed, and should I be testing everything before I muck around any more?[20:39:57] <lunaphyte> if you've selected virtual(8), also provided by postfix, then you use the virtual mailbox domain class, and thus you use virtual_mailbox_domains [and friends][20:41:11] <lunaphyte> if you've selected some other mda software, not provided by postfix, then you use the relay domain class, and thus relay_domains [and friends] - since you are relaying mail off to some other peice of software, which will then handle all of the details of devliery[20:41:22] <lunaphyte> *delivery[20:41:28] <lunaphyte> sure, i'd be testing all along the way[20:41:37] <lunaphyte> haven't you been?[20:42:25] <samgoody> No, because I am very wary of enabling email on a server before knowing it should be stable.[20:42:49] <lunaphyte> oh, well if it's not in use, then it doesn't really matter[20:42:56] <samgoody> So as not to accidentaly open up a relay or something majorly dumb.
