Hello, just upgraded one of my testing machine from dovecot 1.2.15 to 2.0.7. After some trouble with permissions now all seems working, but when I stop dovecot I have these errors in log: Nov 9 17:08:07 in dovecot: master: Warning: Killed with signal 15 (by pid=20362 uid=0 code=kill) Nov 9 17:08:07 in dovecot: pop3-login: Error: read(anvil) failed: EOF Nov 9 17:08:07 in dovecot: imap-login: Error: read(anvil) failed: EOF Nov 9 17:08:07 in dovecot: imap(mailing(a)securitylabs.it): Server shutting down. bytes=410/59361 Nov 9 17:08:07 in dovecot: imap(mailing(a)securitylabs.it): Server shutting down. bytes=79/26605 Nov 9 17:08:07 in dovecot: imap(mailing(a)securitylabs.it): Server shutting down. bytes=802/55708 Nov 9 17:08:07 in dovecot: imap(mailing(a)securitylabs.it): Server shutting down. bytes=258/1242 Nov 9 17:08:07 in dovecot: auth: Error: read(anvil-auth-penalty) failed: EOF Nov 9 17:08:07 in dovecot: auth: Error: net_connect_unix(anvil-auth-penalty) failed: Permission denied dovecot -n: # 2.0.7: /usr/local/etc/dovecot/dovecot.conf # OS: Linux 2.6.32-5-xen-686 i686 Debian squeeze/sid auth_cache_negative_ttl = 2 mins auth_cache_size = 1000 M auth_cache_ttl = 2 mins auth_master_user_separator = * auth_username_chars = abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ01234567890.-_@& disable_plaintext_auth = no dotlock_use_excl = yes first_valid_uid = 100 last_valid_uid = 105 lock_method = dotlock log_timestamp = "%Y-%m-%d %H:%M:%S " login_greeting = Server ready. mail_fsync = never mail_gid = Debian-exim mail_location = maildir:~/Maildir:INDEX=/var/indexes/%d/%n mail_privileged_group = Debian-exim mail_uid = Debian-exim managesieve_notify_capability = mailto managesieve_sieve_capability = fileinto reject envelope encoded-character vacation subaddress comparator-i;ascii-numeric relational regex imap4flags copy include variables body enotify environment mailbox date namespace { inbox = yes location = prefix = separator = / type = private } namespace { location = maildir:~/Maildir/expunged prefix = EXPUNGED/ separator = / type = private } namespace { location = maildir:~/Maildir/deleted prefix = DELETED/ separator = / type = private } namespace { location = maildir:~/Maildir/deleted/expunged prefix = DELETED/EXPUNGED/ separator = / type = private } passdb { args = /usr/local/etc/dovecot-sql.conf driver = sql } passdb { args = /usr/local/etc/passwd.masterusers driver = passwd-file master = yes pass = yes } plugin { lazy_expunge = EXPUNGED/ DELETED/ DELETED/EXPUNGED/ mail_log_events = delete expunge mail_log_group_events = quota = maildir quota_warning = storage=80%% /usr/local/bin/dovecot-quota-warning.sh 80 quota_warning2 = storage=90%% /usr/local/bin/dovecot-quota-warning.sh 90 sieve = ~/.dovecot.sieve } pop3_no_flag_updates = yes protocols = imap pop3 service auth { unix_listener auth-userdb { group = Debian-exim mode = 0600 user = Debian-exim } } service imap-login { client_limit = 256 process_limit = 128 process_min_avail = 3 service_count = 1 } service imap { drop_priv_before_exec = yes process_limit = 256 vsz_limit = 256 B } service pop3-login { client_limit = 256 process_limit = 128 process_min_avail = 3 service_count = 1 } service pop3 { drop_priv_before_exec = yes process_limit = 256 vsz_limit = 256 B } ssl_cert = </usr/local/etc/dovecot.crt ssl_key = </usr/local/etc/dovecot.key userdb { args = /usr/local/etc/dovecot-sql.conf driver = sql } protocol imap { mail_max_userip_connections = 10 mail_plugins = " notify quota imap_quota mail_log lazy_expunge" } protocol pop3 { mail_max_userip_connections = 3 mail_plugins = " notify quota mail_log" pop3_uidl_format = %08Xu%08Xv } protocol lda { mail_plugins = quota sieve postmaster_address = postmaster(a)securitylabs.it } My /usr/local/var/run/dovecot directory: 4 drwxr-sr-x 4 root staff 4096 Nov 9 17:08 . 4 drwxrwsrwx 3 root staff 4096 Nov 9 17:05 .. 0 srw------- 1 root staff 0 Nov 9 17:05 anvil 0 srw------- 1 root staff 0 Nov 9 17:05 anvil-auth-penalty 0 srw------- 1 root staff 0 Nov 9 17:05 auth-client 0 srw------- 1 dovecot staff 0 Nov 9 17:05 auth-login 0 srw------- 1 root staff 0 Nov 9 17:05 auth-master 0 srw------- 1 Debian-exim Debian-exim 0 Nov 9 17:05 auth-userdb 0 srw------- 1 dovecot staff 0 Nov 9 17:05 auth-worker 0 srw------- 1 root staff 0 Nov 9 17:05 config 0 srw------- 1 root staff 0 Nov 9 17:05 dict 0 srw------- 1 root staff 0 Nov 9 17:05 director-admin 0 srw-rw-rw- 1 root staff 0 Nov 9 17:05 dns-client 0 srw------- 1 root staff 0 Nov 9 17:05 doveadm-server 0 lrwxrwxrwx 1 root staff 35 Nov 9 17:05 dovecot.conf -> /usr/local/etc/dovecot/dovecot.conf 4 drwxr-xr-x 2 root root 4096 Nov 9 17:05 empty 4 drwxr-x--- 2 root dovenull 4096 Nov 9 17:05 login My emails are delivered as user Debian-exim and users are virtual in a MySQL DB.

[Dovecot] Dovecot LDA/LMTP vs postfix virtual delivery agent and the x-original-to header

Does anyone know if the use of LMTP (or even the dovecot LDA) still loses the x-original-to header that the postfix vda adds and that I rely heavily on (since I use a lot of aliases), and if it does, is there any solution to get the original recipient added back in before final delivery? Everything I'm reading says that LMTP is better, but I really do need this header (or one like it) to be there so I know who the original recipient was (for filtering and other purposes). Thanks, -- Best regards, Charles

[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 23 Feb '15

23 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
