Last month, around sept 19th, some emails have been delivered with more than 12h lag. I did not receive any mail from this bugzilla since sep 27th. Example: http://bugs.gentoo.org/show_bug.cgi?id=194043 have been commented manu times in october 2nd; today the 4th, I did not yet receive any notification. Still, I keep receiving emails from other people => my email provider service works fine. I never had problems with spam filters, and did not find bugzilla emails in there. Here is an example of what hapenned last month: Received: from mx-out.ocsa-data.net ([127.0.0.1]) by localhost (node2-2.ouvaton.local [127.0.0.1]) (amavisd-new, port 10024) with ESMTP id 7yIUXl7zXNfS for <benoit@demaine.info>; Wed, 19 Sep 2007 17:33:31 +0200 (CEST) Received: from [140.211.166.183] (helo=smtp.gentoo.org) by mx-out.ocsa-data.net with esmtp (Exim - FreeBSD Rulez) id 1IY1YR-0004GM-6n for <dhp_gentoo@doublehp.org>; Wed, 19 Sep 2007 17:33:31 +0200 Received: from kite.gentoo.org (kite.gentoo.org [64.127.104.130]) (using TLSv1 with cipher AES256-SHA (256/256 bits)) (No client certificate requested) by smtp.gentoo.org (Postfix) with ESMTP id 43E2E65641 for <dhp_gentoo@doublehp.org>; Wed, 19 Sep 2007 15:33:30 +0000 (UTC) Received: from apache by kite.gentoo.org with local (Exim 4.60) (envelope-from <bugzilla-daemon@gentoo.org>) id 1IXvpy-0004cl-Pt for dhp_gentoo@doublehp.org; Wed, 19 Sep 2007 09:27:14 +0000 Where Demaine.info and Doublehp.org are my domain, and Ouvaton is my service provider. See how emails are stuck in kite.gentoo.org for hours. On that day, Over night, I received about 15 emails in a shot (with over 12h late), and, about 1h later, 12 more ones. My provider does not have any policy of this kind (nothing like "I only accept 15 emails per hour). I can provide over 20 logs similar to this one. Reproducible: Couldn't Reproduce Steps to Reproduce: 1. create or comment a bug (and tick "notify me") 2. wait ... 3. wait ... could you check why emails are so late, and where are my notifications for bugs modified after 27th sept for me ? Since I am not notified, I dont know anymore what maintainers want from me. It's years I use email notification, and work this way; changing habits would take ages. And some recent bugs are very important (X org 1.4 not working at all, and I keep asking urgent hard mask). If I am not notified maintainers want feedback, we are all stuck. For now, I will try to use the bug filter system by dates, but I dont like it very much.
Around Sept. 18-20 the mailserver has been fairly overloaded due to huge loads of stupid spam attempts, but in past couple of days everything seems back to normal, so really weird you are still not getting any mail.
Jakub: I have not yet been notified or your comment; can you check logs ? Bugzilla clearly can not fall in my spam filter: since I have added it to by address book, even it it was considered spam, emails would be copied to a specific place ... that remains empty. Problem is: are emails being sent to me by bugzilla ? do they reach Gentoo SMTPs ? do they reach my provider ? As test-example, you can search the email that should have been generated by your below comment. I ll keep date filtering for now, but it's REALLY unpractical: I have to go to my browser and select filter rules to know if I have bugs to read ... instead of just opening my mailbox ... Do you have access to logs ?

Thanks, I needed you to do this test. If I just said them "I dont receive emails", they d have answer "proove it" !. Thx.
hmmmm ... did Gentoo operators change anything in the server settings around sept 27th ? Somebody changed something: maybe this broke on that day cause Gentoo ops changed something ... (of course, I asked my service provider the same question :D )
(In reply to comment #5) > hmmmm ... did Gentoo operators change anything in the server settings around > sept 27th ? Not sure what you mean? The above is a *manual* telnet session. It fails. I have no clue what kind of checks does the mailserver perform, but they are obviously broken. Closing UPSTREAM (as in your provider), feel free to reopen once you can show us why is an MTA rejecting @gentoo.org addresses our fault.
(And, it's not just @gentoo.org sender that it rejects), another one follows. In fact, I wasn't able to send you any mail from any email address I tried via the MX server listen in your DNS records. $ telnet mx1.ocsa-data.net 25 Trying 194.36.166.12...

It may not be an upstream problem if ... Gentoo changed (and broke) DNS entries of their machines, SMTP configuration files, the way to present themselves to the receivers ... According to experience, it's likely to be upstream, but there are one or two reasons for "not". I am bored of this, I will change my email feedback address in my profile (likely for my Gmail one). Thanks for support.
Go and read bug 194223 where I just proved that Exim has a bug that causes it to reject mail with a trailing dot on hostnames (which was added in the Reply-To header on Sept 27th). Regarding the mail delays, I don't have logs for Sept 19th anymore, but I don't see any other delays since then for your servers. Next time you see it happen, please contact me asap, we only keep mail logs for ~12 days.
(In reply to comment #9) > (which was added in the > Reply-To header on Sept 27th). Ha rhis been done in Gugzilla ? thus Bugzilla.Gentoo issue ? I have just been notified about this 9th comment; who may have fixed this ? Gentoo ops ? my provider without giving feedback yet ? who did something ?
sorry for typo: "has this been" ...
The mail loss was a change in the bugzilla config (on sept 27th) that hit a recipient-side Exim bug (when the recipient was using Exim). You got the mail because I did a workaround in bugzilla for the Exim bug.
