[Dovecot] Dovecot stops with "Fatal: kevent(): Invalid argument"
by Henrik Larsson 09 Jun '17

09 Jun '17

# 2.0.11: /usr/local/etc/dovecot/dovecot.conf # OS: FreeBSD 8.2-STABLE amd64 Dovecot stops with the following logged: - master: Fatal: kevent(): Invalid argument I have found that a diff was created for "src/lib/ioloop-kqueue.c" for a similar issue: http://dovecot.org/pipermail/dovecot/2010-November/054855.html I have patched my system with this and haven't seen the problem since, but I don't know if this is a coincidence. Could you please explain if the diff should actually fix anything or just add some more logging in case it stops again? Best regards Henrik Larsson

[Dovecot] Plugins: virtuals vs acls
by Leho Kraav 20 Sep '16

20 Sep '16

Hi all dovecot-virtual: * all when dovecot-acl files restrict some subset of * for a user, does dovecot respect these ACLs when collecting messages for virtual folder? I'd like a confirmation about what I should be seeing when I start implementing this setup.

[Dovecot] Patch: 2.0 support for URLAUTH, BURL, CATENATE
by Mike Abbott 18 Apr '16

18 Apr '16

Thank you Timo for beginning the port of URLAUTH, BURL, and CATENATE from 1.2 to 2.0. Attached please find two patches that finish the port to 2.0. One patch updates the dovecot-2.0-urlauth branch and is based on the tip of that branch. The other patch adds the full support to dovecot-2.0.beta5. The resulting URLAUTH/BURL/CATENATE code is the same. Please let me know if you have any questions about these patches. Thanks.

[Dovecot] Sieve vacation not working
by Phill Edwards 24 Feb '15

24 Feb '15

I've been trying all night to get vacation working in my .dovecot.sieve file. The way our email works is we have one account on dovecot which serves my mail and my wife's and we use procmail and sieve to put the emails in different folders depending on who it's for. I'm trying to set up a vacation reply on my wife's email address (aaaaaaaa@optus* below) so people can update to her new address. Here's my file with the email addresses masked: require ["fileinto", "vacation"]; if address :is "to" "xxxxxxxxxxxxxxx(a)ozemail.com.au" { fileinto "Phill_OzEmail_Folder"; stop; } elsif address :is "to" "yyyyyyyyyyyyyyyyy(a)optusnet.com.au" { fileinto "Phill_Optus_Folder"; stop; } elsif address :matches "to" "aaaaaaaa@optus*" { vacation "Please update my email address to bbbbbbbbb(a)exemail.com.au"; fileinto "Sarah_Optus_Folder"; stop; } else { keep; stop; } The problem I'm having is that no auto-replies are sent. I removed .dovecot.lda-dupes and that didn't help; so then I touched it and now it's a 0 byte file and that didn't help. There is no dovecot.sieve.err file and I can't see anything in /var/log/dovecot.log which gives any message about why this wouldn't work. The emails to aaaaaaa@optus* get filed into the right folder so I know the matching is working. I've also tried a reject recipe and that worked fine, so I know that it can send an email if it chooses to. So it's a complete black box mystery as to why it just won't send a reply. Regards, Phill

[Dovecot] RFE: IMAP LIST Extension for Special-Use Mailboxes
by Patrick Ben Koetter 03 Jan '14

03 Jan '14

Timo, would you consider adding support for "IMAP LIST Extension for Special-Use Mailboxes" <http://www.rfc-editor.org/rfc/rfc6154.txt> any time near in the future? I would really love to get rid of all those folders created by all those different mail clients just because they can't agree to use the same folder for special purpose. Obviously clients need to support it too. Having Dovecot support it certainly would make them adopt the standard sooner. p@rick -- state of mind Digitale Kommunikation http://www.state-of-mind.de Franziskanerstraße 15 Telefon +49 89 3090 4664 81669 München Telefax +49 89 3090 4666 Amtsgericht München Partnerschaftsregister PR 563

[Dovecot] execvp /usr/local/libexec/dovecot/dovecot-lda: Permission denied
by Edward Carraro 09 Aug '13

I'm trying to follow the instructions for configuring Dovecot LMTP with postfix for virtual domains but whenever mail arrives, in /var/log/maillog, I see Sep 23 16:01:20 mybox postfix/pipe[572]: 999C83206C6: to=< user(a)mytest.domain.com>, relay=dovecot, delay=0.08, delays=0.04/0.01/0/0.03, dsn=4.3.0, status=deferred (temporary failure.

[Dovecot] Wrong remote IP (rip) in mail.log using IMAP login
by tyli 02 Aug '13

02 Aug '13

Dear list users While trying to secure our dovecot server with fail2ban I came across the following problem: We use dovecot (1.2.9, ubuntu package) behind a NAT, and failed login attempts are logged with our firewall as the remote ip. Example: Apr 15 08:36:26 mail dovecot: imap-login: Disconnected (auth failed, 6 attempts): user=<xy>, method=PLAIN, rip=192.168.0.1, lip=192.168.0.3 Therefore I would ban 192.168.0.1 which means that I ban EVERY user. Funny thing is that POP3 login attempts are logged correctly: Apr 13 11:05:50 mail dovecot: pop3-login: Disconnected (auth failed, 1 attempts): user=<sgvyniwx>, method=PLAIN, rip=217.81.27.55, lip=192.168.0.3 Any ideas how to change this? Thanks in advance tyli

[Dovecot] Proxying improvements in v2.1.2
by Timo Sirainen 16 Jul '13

16 Jul '13

I just committed a couple of features that will make life easier for some types of proxying setups: 1. IMAP proxying has already for a while supported sending local/remote IP/port to backend server, which can use it for logging and other purposes. I've now implemented this for POP3 as well, although only the remote IP/port is forwarded, not local IP/port. I implemented this also for LMTP in v2.2 tree, but haven't bothered to backport that change. Both POP3 and LMTP uses XCLIENT command that is compatible to Postfix's (XCLIENT ADDR=1.2.3.4 PORT=110). 2. proxy_maybe=yes + host=host.example.com actually works now. As long as host.example.com DNS lookup returns one IP that belongs to the current server the proxying is skipped. 3. auth_proxy_self = 1.2.3.4 setting means that if proxy_maybe=yes and host=1.2.3.4 then Dovecot assumes that this is a local login and won't proxy it, even if 1.2.3.4 isn't the actual local IP. This can be helpful if the host field contains load balancer's IP address instead of the server's. You can add more than one IP (space separated) and of course everything related to this works just as well with hostnames as with IPs (even when hostname expands to multiple IPs).
