Pacaging/build issues with AIX and vac (dovecot-2.2.25)
by Michael Felt 10 Jun '17

10 Jun '17

Hi. I finally decided it was really time to stop being lazy and really move away from gmail. After I have a server in my basement using power, etc. So I turned on the imap provided - and did not quite cry - it will have to do for now, but imap2 is wanting. A real server yes, but not Linux. (Using linux would require another server AND I would feel I am being lazy again). So, I downloaded dovecot-2.2.25 and tried to build. Configure (messages to stderr) xlc is /usr/vacpp/bin/xlc + CPPFLAGS="-I/opt/include -I/opt/buildaix/include" CFLAGS="-I/opt/include -O2 -qmaxmem=-1 -qarch=pwr5 -I/opt/buildaix/includes ./configure\ --prefix=/opt \ --sysconfdir=/var/dovecot/etc\ --sharedstatedir=/var/dovecot/com\ --localstatedir=/var/dovecot\ --mandir=/usr/share/man\ --infodir=/opt/share/info/dovecot \ > .buildaix/configure.out xlc_r: 1501-216 (W) command option -dM is not recognized - passed to ld xlc_r: 1501-228 (W) input file c not found 1506-297 (S) Unable to open input file null.

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

Fatal error with IMAP MOVE from a shared mailbox to Trash folder
by Daniele Barresi 30 May '17

30 May '17

Hello everyone. I have a problem using Dovecot 2.2.26 with ACL plugin and deleting e-mails from a shared mailbox. My user doesn't have the "expunge" permission on the shared mailbox, but it has the "write-deleted" permission. So, when I delete a message from the shared mailbox using a client that implements the IMAP MOVE command, it tries to move the message to my Trash folder. Then the server closes the connection to the client (process aborted) and I get three lines in the log file with a backtrace and "Fatal" error. In this case the message doesn't get copied or moved from the shared folder and the client complaints. I found the same thing happens whenever I try to move anything between folders of the shared mailbox itself, while logged in with my user. I can move messages inside my own mailbox just fine. If I try the same operation from a client that uses the IMAP COPY + DELETE commands, no errors are logged and the outcome is as expected: the message gets copied from the shared folder to my Trash and gets the flag "\Deleted" set on the shared folder.

I tested and reproduced the error with Thunderbird and Roundcube. The Apple Mail client uses IMAP COPY + DELETE, instead of IMAP MOVE, and no errors are reported. So I think it's related to the IMAP MOVE implementation on Dovecot server. Has anyone seen the same error? Any suggestions? Is this a Dovecot bug? --- Daniele Barresi

Plugin "mail_crypt" - using folder keys
by Evgeniy Korneechev 26 May '17

Hi, i have two questions about using "folder keys" for encryption: 1. If i use this method how can i decrypt files manually? 2. If move a letter to another folder (or remove it), it will be unreadable.

[Sieve] Is the way to run external script to get attachment?
by Konstantin Shalygin 22 Mar '17

22 Mar '17

Hello. Read all about Extprograms, but have a question. Use case: Every day we have couple messages with attachment (from one sender, this is one-way communication). This attachment is uploads to ownCloud. By hand... need some automation. As I see, pipe cat execute scripts with text data USER/FROM/SUBJECT - and I think with variables it can be any text data, how about attachment? How I see this: script executes and as arg receives from sieve attachment file, or message file and we can parse it for attachment. When we have attachment - upload to ownCloud via RESTapi and purge message. Found some realization for encrypt messages https://github.com/EtiennePerot/gpgit/blob/master/encmaildir.sh but for me more easy just connect to IMAP and do what I want (but I love sieve). Thanks. <http://wiki.dovecot.org/Pigeonhole/Sieve/Plugins/Extprograms>

Is it possible to use sieve when delivering via pipe to the dovecot deliver command ?
by Thomas Carrié 21 Mar '17

21 Mar '17

Hello, I am using Exim with this delivery configuration: virtual_delivery: driver = pipe command = /usr/lib/dovecot/deliver -d $local_part@$domain -f ... I have enabled manage-sieve and uploaded a simple sieve script that I can see on the server. man page of /usr/lib/dovecot/deliver says it supports sieve. Mail debug is enabled: $ dovecot -n | grep debug mail_debug = yes Delivering a mail shows only this line in dovecot log: Jan 21 17:38:51 myserver dovecot: lda(joe(a)something.com): msgid=<20170121183537.7313f219@homenetwork>: saved mail to INBOX According to page http://wiki2.dovecot.org/Pigeonhole/Sieve/Troubleshooting#Sieve_Scripts_are… I should have a log saying that the sieve plugin is loaded Here is the sieve relevant parts of dovecot -n: # 2.2.13: /etc/dovecot/dovecot.conf ... plugin { sieve = ~/.dovecot.sieve sieve_dir = ~/sieve } ... protocols = " imap sieve pop3 sieve" ... protocol lda { mail_plugins = " sieve" } Is there a requirement to use delivery via service (unix socket) so that sieve is enabled? Or is there a configuration thing I forgot ? Thank you for your help Thomas

[Bug] Mailbox aliases still broken
by azurit＠pobox.sk 20 Mar '17

20 Mar '17

Hi, about an year ago i was reporting a bug in mailbox aliases, which remains unfixed and unasnwered (probably totally ignored, don't understand why). I thought it was because the bug is old and already fixed but yesterday i upgraded to Dovecot 2.2.24 and problem persists. Here is the original report, everything, except the Dovecot version, is still correct: http://dovecot.org/list/dovecot/2015-June/101176.html Will this be fixed? Thanks for info. azur

Replication Troubles
by Wolfgang Hennerbichler 16 Mar '17

16 Mar '17

Hi Dovecot Users, I’ve configured dovecot dsync replication and I see troubles in the logs and get user complaints which I can’t explain. I found similar threads on this mailinglist, but I couldn’t find a solution anywhere. Does anybody have dsync running without problems on a high volume mailserver? I see the following logs, examples given: Feb 17 18:16:49 dovecot dovecot: imap(zoechi): Warning: /var/mail/zoechi/dovecot-uidlist: Duplicate file entry at line 10395: 1487350019.M138380P28563.dovecot.wogri.at,S=18930,W=19377 (uid 41092 -> 41093) - retrying by re-reading from beginning with this one I’m not sure - it might be that this is completely OK because due to replication UIDs clash. Maybe that’s OK, but I couldn’t find a confirmation. Feb 17 18:16:49 dovecot dovecot: imap(zoechi): Warning: Maildir /var/mail/zoechi: Expunged message reappeared, giving a new UID (old uid=41092, file=1487350019.M138380P28563.dovecot.wogri.at,S=18930,W=19377) This one is definitely a problem, deleted messages re-appear in the mailbox. I made sure that the 2 hosts doing replication have different hostnames. I run 2.2.27 (from debian-jessie backports). Config below. Thanks for hints (or pointers to other example configs where dsync works without problems) # dovecot -n # 2.2.27 (c0f36b0): /etc/dovecot/dovecot.conf # Pigeonhole version 0.4.16 (fed8554) # OS: Linux 4.8.14 x86_64 Debian 8.7 ext4 auth_verbose = yes debug_log_path = /var/log/dovecot.debug doveadm_password = # hidden, use -P to show it first_valid_gid = 106 first_valid_uid = 104 hostname = localhost last_valid_gid = 106 last_valid_uid = 104 mail_gid = dovecot mail_location = maildir:/var/mail/%n mail_plugins = quota fts fts_lucene virtual notify replication mail_temp_dir = /var/lib/dovecot/tmp mail_uid = dovecot 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 index ihave duplicate mime foreverypart extracttext editheader namespace { list = children location = virtual:/var/mail/%n/virtual prefix = virtual. separator = . } namespace inbox { inbox = yes list = yes location = mailbox "Deleted Messages" { auto = subscribe special_use = \Trash } mailbox Drafts { special_use = \Drafts } mailbox Junk { special_use = \Junk } mailbox Sent { special_use = \Sent } mailbox "Sent Messages" { auto = no special_use = \Sent } mailbox Spam { auto = subscribe special_use = \Junk } mailbox Trash { special_use = \Trash } prefix = separator = . subscriptions = yes type = private } passdb { args = /etc/dovecot/dovecot-ldap.conf.ext driver = ldap } plugin { default_language = de fts = lucene fts_lucene = whitespace_chars=@. mail_replica = tcp:172.16.1.1:12345 quota = maildir:User quota quota_rule = *:storage=5G quota_rule2 = Trash:storage=+200M quota_rule3 = Spam:ignore quota_warning = storage=95%% quota-warning 95 %u quota_warning2 = storage=80%% quota-warning 80 %u sieve = /etc/sieve/%n.sieve sieve_default = /etc/sieve/default.sieve sieve_dir = ~/sieve sieve_extensions = +editheader } pop3_deleted_flag = $POP3Deleted postmaster_address = postmaster(a)wogri.at protocols = " imap lmtp sieve pop3" service aggregator { fifo_listener replication-notify-fifo { user = dovecot } unix_listener replication-notify { user = dovecot } } service doveadm { inet_listener { port = 12345 } } service imap { process_limit = 1024 } service lmtp { inet_listener lmtp { port = 2003 } unix_listener lmtp { user = dovecot } user = dovecot } service managesieve-login { inet_listener sieve { port = 4190 } service_count = 1 } service pop3 { process_limit = 1024 } service quota-warning { executable = script /usr/local/sbin/quota-warning.sh unix_listener quota-warning { user = dovecot } user = dovecot } service replicator { process_min_avail = 1 unix_listener replicator-doveadm { mode = 0600 } } ssl = required ssl_cert = </etc/dovecot/server.cert.pem ssl_key = # hidden, use -P to show it userdb { args = /etc/dovecot/dovecot-ldap.conf.ext driver = ldap } protocol lmtp { mail_plugins = quota sieve virtual notify replication } protocol lda { mail_plugins = quota fts fts_lucene virtual notify replication sieve } protocol imap { mail_max_userip_connections = 50 mail_plugins = quota fts fts_lucene virtual notify replication imap_quota } protocol pop3 { mail_plugins = quota fts fts_lucene virtual notify replication } local 2a00:XXX::/64 { doveadm_password = # hidden, use -P to show it }
