Permissions for new folders
by David Cigánek 08 Apr '16

08 Apr '16

Hi, I have a problem with permissions for newly created folders in Dovecot. Everything worked fine until few days ago, when i did a little change in userdb lookup - but i don't know why it is causing problems. Server uses following directory structure: index - /data/mail/index mail - /data/mail/mail alt - /data/mail/archive all 3 on separate volumes, for performance reasons. Up until few days, i used following: # doveadm user dave(a)example.com field value user dave(a)example.com uid 13726 gid 1004 home /data/mail/mail/003/3726/da/dave mail mdbox:~/mbox/:DIRNAME=.00f-dbox-Mails:INDEX=/data/mail/stub/index/data/mail/mail/003/3726/da/dave:ALT=/data/mail/stub/archive/data/mail/mail/003/3726/da/dave config is quite simple: mail_location = mdbox:~/mbox/:DIRNAME=.00f-dbox-Mails:INDEX=/data/mail/stub/index%h:ALT=/data/mail/stub/archive%h passdb { driver = sql args = /data/mail/sql/dovecot-sql.conf.ext } userdb { driver = static args = gid=vmail } from SQL i get those fileds username domain password userdb_home userdb_uid userdb_quota_rule userdb_quota_over_flag For nicer paths, i created a symlinks /data/mail/stub/index/data/mail -> /data/mail/index /data/mail/stub/archive/data/mail -> /data/mail/archive so path /data/mail/stub/index/data/mail/mail/003/3726/da/dave is in fact in /data/mail/index/003/3726/da/dave In that setup, everything worked fine, but i didn't like those simlinks, so i altered the SQL query to return all paths in userdb_mail filed: # doveadm user dave(a)example.com field value user dave(a)example.com uid 13726 gid 1004 home /data/mail/mail/003/3726/da/dave mail mdbox:~/mbox/:DIRNAME=.00f-dbox-Mails:INDEX=/data/mail/index/003/3726/da/dave:ALT=/data/mail/archive/003/3726/da/dave So everything is in fact the same but little nicer. But since then, newly created directories doesn't get the same permissions like parent folder as day should (2770), but instead they are created with 2700: # stat -c "%a (%A)" /data/mail/mail/ 2770 (drwxrws---) # stat -c "%a (%A)" /data/mail/mail/003 2700 (drwx--S---) I need to have there 2770 perms, especialy because when other user like this is created: user dave(a)example.com uid 13999 gid 1004 home /data/mail/mail/003/3999/da/dave Dovecot is unable to create directory /data/mail/mail/003/3999, because it doesn't have write permissions for group on /data/mail/mail/003. I can't find any reason for this behavior - is it something in Dovecot or am I doing something wrong?

Broken pipe with own dict server. Timing issue?
by martijn.list 08 Apr '16

08 Apr '16

Hi, I have created my own dict server (proxy:[<dict path>]:<destination dict>) to access a proprietary database. The dict server basically creates a listing socket on a separate thread and then waits for incoming requests with accept(handle, NULL, 0). When a request comes in (i.e., when accept returns the accepted socket fd), the request is handed over to a handler thread (from a thread pool). The handler thread then read from the input. The issue that I have is that if the read is done too fast after the accept, Dovecot reports a broken pipe: dovecot: auth-worker(19904): Error: write(/usr/share/test-server/tmp/test-dict) failed: Broken pipe This happens for almost all processes that try to access the dict server. However If I add some sort of delay between the accept call and read (for example a sleep), everything works. No broken pipe even after testing with a large number of parallel requests for a long time. Somehow it looks like if the first read is done too fast, it takes a long time to read the data. During this time it looks like all other Dovecot processes are no longer able to connect and report the broken pipe. With the artificial delay, everything works ok and I can see that multiple incoming request are handled by multiple threads so it looks like Dovecot uses multiple auth worker processes. If however one connection hangs on the read it looks like no Dovecot proccess is able to connect Any idea what might be causing the broken pipe in relation to timing of the read? Kind regards, Martijn

Own implementation of a dict server. Is dict lookup multi threaded or single threaded?
by martijn.list 08 Apr '16

08 Apr '16

Hi, I have created my own dict server (proxy:[<dict path>]:<destination dict>) to access a proprietary database. What happens if the dict server lookup is slow? for example because the lookup process takes some time? Does Dovecot access the dict proxy from multiple threads or is this a single threaded process? Kind regards, Martijn Brinkers

ETOOMANYREFS related errors
by Luis Ugalde 07 Apr '16

07 Apr '16

Hi, I'm starting to see, on a pretty standard Debian Jessie installation, some error messages that are apparently related to the ETOOMANYREFS errno. Firstly, the mail log shows this: dovecot: pop3-login: Error: fd_send(pop3, 18) failed: Too many references: cannot splice And then the login process fails: dovecot: pop3-login: Internal login failure (pid=34388 id=1) (internal failure, 1 successful auths): user=<username>, method=PLAIN, rip=rip, lip=lip, session=<session> Is this something that Dovecot should be able to handle, or is it strictly Debian/libc/MySillyMistake related? #uname -a Linux server 3.16.0-4-amd64 #1 SMP Debian 3.16.7-ckt20-1+deb8u3 (2016-01-17) x86_64 GNU/Linux #dovecot --version 2.2.13 #dpkg -l | grep -E 'dovecot-core|libc6|linux-image' ii dovecot-core 1:2.2.13-12~deb8u1 amd64 ii libc6:amd64 2.19-18+deb8u3 amd64 ii libc6-i386 2.19-18+deb8u3 amd64 ii linux-image-3.16.0-4-amd64 3.16.7-ckt20-1+deb8u3 amd64 Best Regards, Luis

lmtp_rcpt_check_quota = yes silently blocks mail if quota check fails
by Tom Sommer 07 Apr '16

07 Apr '16

I have a user which has a quota-check that fails with 'Internal error', if I enable lmtp_rcpt_check_quota, the mail is silently tempfailed. Actually it looks like lmtp_rcpt_check_quota=yes suppresses normal Info/Error logging, even on Director. The MTA just gets " 451 4.3.0 <xxxx(a)xxx.xxx> Temporary internal error (in reply to end of DATA command)" from the director, but nothing is logged with lmtp_rcpt_check_quota=yes, anywhere. -- Tom

doveadm sync -1 -R
by Lukas Kolbe 07 Apr '16

07 Apr '16

Hi, I’m migrating an old Zarafa-installation to a dovecot using mdbox and sis on Debian Jessie. To copy over the emails, I use doveadm backup on the new box - or more precisely: vmail# doveadm -v -o imapc_user=$user -o imapc_password=$pass -o imapc_host=$host -o imapc_features=rfc822.size -o imapc_port=993 -o mailbox_list_index=no -o imapc_ssl_verify=no backup -R -x "Public folders*" -x "Public folders/*" -u $user imapc: For each invoke of doveadm backup -R, the local (new) mailbox gets wiped and all mails are retransferred - so far, so good. I’d like to use "doveadm sync -1“ as per the manpage to keep the downtime short, however sync doesn’t like the -R option: sync: invalid option -- 'R' doveadm sync [-u <user>|-A] [-S <socket_path>] [-1fPU] [-l <secs>] [-r <rawlog path>] [-m <mailbox>] [-g <mailbox_guid>] [-n <namespace> | -N] [-x <exclude>] [-s <state>] -d|<dest> If I understand it correctly, without -R it would mean that doveadm sync would incorporate the changes from the local dovecot-mailbox into the remote imapc:-Mailbox, which is the opposite of what I want. Dovecot version is current head as of yesterday. Is what I’m trying to do even possible with doveadm sync? Kind regards, Lukas

What is dovecot.socket and do i need it?
by Hamy 07 Apr '16

07 Apr '16

Helloafter rebooting the server, i keep getting these errors in mail.err : Apr 7 06:08:09 main dovecot: master: Error: systemd listens on port 143, but it's not configured in Dovecot. Closing. Apr 7 06:08:09 main dovecot: master: Error: systemd listens on port 993, but it's not configured in Dovecot. Closing. Apr 7 06:08:09 main dovecot: master: Error: systemd listens on port 993, but it's not configured in Dovecot. Closing. And then dovecot refuses any connection. the problem is solved if i do a manual restart of dovecot.service. After some search, i found 2 different solutions, one suggesting disabling dovecot.socket completely, the other one adjusting its settings: https://sowhatisthesolution.wordpress.com/2015/04/27/upgrading-dovecot-debi… I also found an old thread in the mailing list that might be relevant: http://dovecot.org/list/dovecot/2012-March/134376.html The errors indeed seem to go away if i disable dovecot.socket . I would be grateful is someone could help me understand the role of dovecot.socket , and why that error happens and what is the right way to solve it? PS: I am using Ubuntu server 15.10 and dovecot package v2.2.18 Best Regards,

"Lost" e-mail after alternate partition offline
by Daniel van Ham Colchete 07 Apr '16

07 Apr '16

Hey guys! I've got a problem here and I wish you could help me. A drive failed here and went offline for some time. This was a alternate storage drive so it took a while (hours) for us to notice. There was a problem with DRBD also, so it didn't move to the redundancy, it just went offline. I was able to recover all the files there, but a few of my users still don't see their old e-mails, the ones that are supposed to be on the alternate storage. >From what I could troubleshoot here file are there, vmail user can access them, so it's not a permission issue, but a doveadm dump on the index file of each mail folder, won't show the e-mail at the alternate storage drive. So, they are there (at the filesystem), but they aren't (from a imap client). Is there a way to rebuild the dovecot.index file, re-adding everything back to each folder? Best, Daniel Colchete
