I've got an odd error that is coming up and I can't quite put my finger on it. I have 3 mail servers running qmail/vpopmail (5.4.10) and MySQL 3.23.58. I also have mysql replication running and vpopmail is configured in accordance with that (reads on localhost, writes on the db server). We've been receiving complaints from customers about intermittent smtp errors and when I tail the maillog I'm seeing errors like this:
Sep 22 08:58:37 qmail1 vpopmail[64930]: vchkpw-smtp: vpopmail user not found [EMAIL PROTECTED]:1.2.3.4 Sep 22 08:58:39 qmail1 vpopmail[64995]: vchkpw-smtp: vpopmail user not found [EMAIL PROTECTED]:1.2.3.4 Sep 22 08:58:40 qmail1 vpopmail[65022]: vchkpw-smtp: vpopmail user not found [EMAIL PROTECTED]:1.2.3.4 In the interest of our users' privacy I have replaced the various email & ip addresses with the [EMAIL PROTECTED] and 1.2.3.4. What's strange is that it's not happening with any other authentication method (pop3, imap, etc), only smtp. It fails out saying "user not found" and yet a 'vuserinfo' on that user reveals they actually do exist. I have qmail patched with the smtp auth patch from: http://members.elysium.pl/brush/qmail-smtpd-auth/ I'm happy to provide any other information that might be helpful in figuring this out. Any suggestions are, of course, welcomed. Thanks, Clayton
