Move mail behavior
by Martin Stigge 27 Nov '14

27 Nov '14

Hi! I've recently migrated my IMAP mail setup from a server running an older Debian Squeeze with dovecot 1.2.15 to a new Debian Jessie system with dovecot 2.2.13. In the old setup, it used to be so that a mail moved from a folder to another one was marked as deleted in the originating folder (in dovecot 1.2.15). In the new setup, the mail just disappears from the originating folder (with dovecot 2.2.13). The mail arrives properly in the target folder, so that's fine. But I actually liked the old behavior. I observe this with Evolution as well as Icedove (Thunderbird) mail clients, which is why I assume that it's actually a change in the IMAP server behavior. Is it supposed to behave like that? Is there a way to configure this? Regards, Martin

2.2.15: SMTP submission server?
by Ron Leach 27 Nov '14

27 Nov '14

List, we're migrating to 2.2 from a 1.x version. There has been mention from time to time of a dovecot SMTP submission server. Last I saw was Timo suggesting this would be a 2.3 feature, but that there was already a 'basic' capability in 2.2 that, more or less, merely provided a secured/authorised SMTP submission. I haven't found anything about this in the wiki, but the feature is of interest to us. I would like to *not* have our MTA capable of being exploited as a relay (it isn't, at the moment) whereas users are logging into our dovecot from offsite using imaps with passwords. While moving to 2.2, I'd like to try to use a secure SMTP submission *separate* from the MTA so that that software, with whatever vulnerabilities or weaknesses it might have, remained locked down and could not relay, if at all possible. (Imaps with passwords means the login details are not transmitted in cleartext and, so, leak no security to an observer of the communications channel. Doubtless there are other weaknesses somewhere but, at least, when using hotel wifi, for example, there is little chance of revealing login details to a packet sniffer. It won't be perfect, there are probably other vulnerabilities, not least in the underlying OSs at each end, but the connection - which is a serious vulnerability in many places - will be as good as is practical to make it.) So, is there some kind of SMTP submission service for a logged in dovecot user, and how would a client make use of that? Is it possible to setup 2.2.15 for this? And, crucially, would the connections between the client (eg at a hotel in some unreliable location) be encrypted right from the start, not using STARTTLS, as is the case in imaps? And, just to be really demanding, could we configure its use on a non-standard port? regards, Ron

2.2.15 Panic in mbox_sync_read_next_mail()
by Hans Morten Kind 27 Nov '14

27 Nov '14

It might not be a fault in dovecot, as the user is accessing the folder locally with alpine while also running imap-sessions. However it would have been nice with a more graceful action than panic? The panic is preceeded by Error: Next message unexpectedly corrupted in mbox file PATH Panic: file mbox-sync.c: line 152 (mbox_sync_read_next_mail): assertion failed: (sync_ctx->input->v_offset != mail_ctx->mail.from_offset || sync_ctx->input->eof) At #7 in the enclosed backtrace the actual values are sync_ctx->input->v_offset = 564 mail_ctx->mail.from_offset = 564 sync_ctx->input->eof = 0 Some will recommend convertion to maildir, but with 25 years history, thousands of active users and dozens terrabytes of mboxes, we are not even considering it. hmk GNU gdb 6.8 Copyright (C) 2008 Free Software Foundation, Inc.

Pigeonhole, vacation being sent incorrectly
by Harry Mills 26 Nov '14

26 Nov '14

Hi, I have an issue with a vacation message in a sieve script. I can't see an error in the script itself. Pigeonhole version: 0.4.2-32 Dovecot Version: 2.2.10 The script was created by Ingo (part of the Horde suite), but I think the script is fine. The problem is that when a message is sent to the "everyone" group (and alias for every person in the organisation), vacation messages are being sent back which I believe is an error. The script is: =============================================== # Sieve Filter # Generated by Ingo (http://www.horde.org/apps/ingo/) (11/11/14, 5:20:06 pm GMT) require ["vacation", "regex", "fileinto"]; # Vacation if allof ( not exists "list-help", not exists "list-unsubscribe", not exists "list-subscribe", not exists "list-owner", not exists "list-post", not exists "list-archive", not exists "list-id", not exists "Mailing-List", not header :comparator "i;ascii-casemap" :is "Precedence" ["list", "bulk", "junk"], not header :comparator "i;ascii-casemap" :matches "To" "Multiple recipients of*" ) { if header :regex "Received" "^.*(2014) (\$.*\$ )?..:..:.. (\$.*\$ )?((\\+|\\-)[[:digit:]]{4}|.{1,5})( \$.*\$)?$" { if header :regex "Received" "^.*(Nov) (\$.*\$ )?.... (\$.*\$ )?..:..:.. (\$.*\$ )?((\\+|\\-)[[:digit:]]{4}|.{1,5})( \$.*\$)?$" { if header :regex "Received" "^.*(13|14|15|16|17|18) (\$.*\$ )?... (\$.*\$ )?.... (\$.*\$ )?..:..:.. (\$.*\$ )?((\\+|\\-)[[:digit:]]{4}|.{1,5})( \$.*\$)?$" { vacation :days 7 :addresses "user2" :subject "Out of office" "IMPORTANT MESSAGE^M THE MESSAGE "; } } } } =============================================== The user "User2" sent a vacation message back to the sender "user(a)example.com" in response to this message (headers only): =============================================== Return-path: <User(a)example.com> Envelope-to: everyone(a)example.com Delivery-date: Thu, 13 Nov 2014 16:08:16 +0000 Received: from tunis.Exampledomain.local ([192.168.254.107] helo=Tunis) by mail.example.com with esmtp (Exim 4.72) (envelope-from <User(a)example.com>) id 1XowwM-0007Qw-Cj for everyone(a)example.com; Thu, 13 Nov 2014 16:08:10 +0000 From: "User" <User(a)example.com> To: "Everyone at Example" <everyone(a)example.com> Subject: Electrician Date: Thu, 13 Nov 2014 16:08:10 -0000 Organization: Example Consultancy Message-ID: <02e601cfff5c$051ec350$0f5c49f0$(a)example.com> MIME-Version: 1.0 Content-Type: multipart/alternative; boundary="----=_NextPart_000_02E7_01CFFF5C.051FD4C0" X-Mailer: Microsoft Outlook 14.0 Thread-Index: Ac//W17ujWbs6KgRRsOZFc7+qT45Tg== Content-Language: en-gb X-Spam-Note: SpamAssassin run bypassed - sent from local address This is a multipart message in MIME format. =============================================== I have checked RFC 5230 section 4.5 which states: "Vacation" MUST NOT respond to a message unless the recipient user's email address is in a "To", "Cc", "Bcc", "Resent-To", "Resent-Cc", or "Resent-Bcc" line of the original message. I cannot see the address for "user2(a)example.com" in any of those fields, or indeed referenced anywhere in the email. Is this a bug, or am I misunderstanding something?

imap-login segfaults when using post-login
by Nico Rittner 26 Nov '14

26 Nov '14

hello, i get these lines in syslog when using post-login within imap-login: imap-login: Fatal: master: service(imap-login): child 574 killed with signal 11 (core dumps disabled) imap[5523]: segfault at 14 ip b7556276 sp bfc1c940 error 4 in libdovecot.so.0.0.0[b7529000+d4000] these are the relevant sections i added: service imap-login { executable = imap post-login } service post-login { executable = script-login /path/to/exec } i also used /bin/true as /path/to/exec to exclude the used exec itself as the reason. same result. version is 2.2.13 on gentoo-linux. i wonder if this error is gentoo-specific (cflags/etc...) or a bug in dovecot. this behaviour can be reproduced on two other of my gentoo-machines. same configuration worked in previous versions, don't know the exact version number. thanks a lot for your suggestions. i'll also cc to the gentoo-people. nico
