Hi, I have an email client that is currently unable to send mail through imap. I am getting a ton of errors in dovecot-imap.log. All of these errors continue to show up, even after purging the dovecot*.* files from the offending folders. This happens to all email accounts on the server. Clearing the cache files doesn't fix, the error appears pretty much immediately after the new cache is generated. ============================== Error: mmap() failed with file path/Maildir/dovecot.index.cache: Invalid argument ============================== These errors are associated with an account unable to send right now. They seem to have only started since the send problem started. ============================== Error: Corrupted transaction log file path/Maildir/dovecot.index.log seq 5: indexid changed 1512100549 -> 1512183737 (sync_offset=0) Error: Index path/Maildir/dovecot.index: Lost log for seq=5 offset=12576: Failed to map file seq=178 offset=40..18446744073709551615 (ret=0) Warning: fscking index file path/Maildir/dovecot.index Error: Fixed index file path/Maildir/dovecot.index: log_file_seq 5 -> 179 IMAP session state is inconsistent, please relogin. in=26 out=1276 ============================== This error is also associated with the offending email client ============================== message repeated 9 times: [ imap(emailaddress): Error: Transaction log path/Maildir/dovecot.index.log: duplicate transaction log sequence (2)] ============================== Some additional info: dovecot: 2.2.22 (fe789d2) Ubuntu Server 16.04 Running on a qemu VM installed on an Unraid 6.3.5 Server 4GB RAM mail folder is located on virtio 9p2000 host passthru fs located on the same physical machine as the VM. Anyone have any ideas? Need additional information? Thanks, Eric

Lua Auth
by Mark Moseley 02 Dec '17

Just happened to be surfing the docs and saw this. This is beyond awesome: https://wiki2.dovecot.org/AuthDatabase/Lua Any words of wisdom on using it? I'd be putting a bunch of mysql logic in it. Any horrible gotchas there? When it says 'blocking', should I assume that means that a auth worker process will *not* accept any new auth lookups until both auth_passdb_lookup() and auth_userdb_lookup() have completed (in which I'd be doing several mysql calls)? If that's the case, I assume that the number of auth workers should be bumped up. And is a 2.3 release fairly imminent?

Autoreplies are not sent
by Sergio Belkin 01 Dec '17

Hi, Let's say I have 2 domains: - Virtual Mailbox Domain: example.local (internal domain) - Virtual Alias Domain: example.com (public domain) Every mail sent to @example.com is really sent to @example.local. I have a virtual alias that forward mails sent to support-abc(a)example.com is sent finally to: op1(a)example.local Now, I'd want to every mail was sent to support-abc(a)example.com it triggers an autoreply vacation style. So, I've wrote and compiled a sieve filter, something like that and put in op1(a)example.local sieve folder. But it fails complaining like that: nov 29 15:55:39 muteriver.example.local dovecot[12549]: lmtp(12675, op1(a)example.local) CqNdF6sCH1qDMQAAcSFsIQ: sieve: msgid=< ded22f3d-f1e3-157e-0667-ca73d851d1a8(a)example.com>: discarding vacation response for implicitly delivered message; no known (envelope) recipient address found in message headers (recipient=<op1(a)example.local>, and additional `:addresses' are specified) I've tried appending in dovecot configuration: lda_original_recipient_header = X-Original-To But it does not work either. Using: dovecot-pigeonhole-2.2.10-8.el7.centos.x86_64 and postfix-2.10.1-6.el7.x86_64 Please could you help me? Thanks in advance! -- -- Sergio Belkin LPIC-2 Certified - http://www.lpi.org
