Optional mail attribute in ldap
by Alexandros Soumplis 17 Nov '14

17 Nov '14

Hello, I am using an ldap database (active directory) for dovecot authentication and I am trying to change the mail location for some users only, thus any mail should be delivered to the default location unless the ldap query returns a successful result which defines the mail variable. I have chosen the AD atttribute "otherMailbox" and added for the required user the value "=mail=mdbox:/newmailboxes/%Lu/". It seems not to work and mails still get delivered to the default location. Any suggestions ? a.

Understanding filesystem quotas
by Chris Szilagyi 15 Nov '14

15 Nov '14

Hello: I've been trying to set up filesystem quotas for IMAP, and cannot seem to get it to work. In IMAP clients it either shows quota unavailable or unknown. I've read the documentation several times. I've enabled the quota plugins and to my knowledge that part is good. I've edited the file 90-quota.conf and uncommented these lines and set them as follows: plugin { quota_rule = *:storage=1G } plugin { quota = fs:User quota:user } To my knowledge, this should enable filesystem quotas by user. However when I run "doveadm quota get -u username", it shows: Quota name Type Value Limit % User quota STORAGE 0 - 0 So basically all zeros. I've also tried running "doveadm -Dv quota get -u username" and don't see anything that stands out or that would indicate an issue. It shows the correct block device and such. I know filesystem quotas are working as I can run "quota username" and it shows the usage. The reason I picked filesystem quotas is because we have /var/spool/mail/username (spool file), and /home/username/mail on the same partition, and because it sounds like it's fast and doesn't require disk I/O. But I'm trying to also figure out by setting the "storage=" command in Dovecot, do I even need to set a hard and soft limit on the filesystem quota then? I would prefer to let Dovecot enforce quotas rather than rely on the filesystem quota mechanism, but keep disk I/O down. Any help would be greatly appreciated on this. Thank you. -- Chris

Using dovecot-lda with sendmail
by Chris Szilagyi 15 Nov '14

15 Nov '14

Hello: I'm trying to get dovecot-lda to work with sendmail on a CentOS 7 server. I've tried following the instructions at the wiki, http://wiki2.dovecot.org/LDA/Sendmail, by adding the lines to /etc/mail/sendmail.mc, recompiling to /etc/mail/sendmail.cf and restarting sendmail -- the process for any sendmail config change. However it is still not working and in the maillog, it shows: sendmail[31949]: sAEM4GTt031742: to=<user@localhost>, ctladdr=<test@localhost> (1000/1000), delay=00:08:31, xdelay=00:00:00, mailer=local, pri=210942, dsn=4.0.0, stat=Deferred: local mailer (/usr/libexec/dovecot/dovecot-lda) exited with EX_TEMPFAIL I verified that SELinux is not interfering in this case. I see talk of having sendmail run /usr/libexec/dovecot/dovecot-lda as other users, but I see that the file on my system is uid/gid as: root/root. Is there a way to get this working? Thanks much! -- Chris

Evolution clientware and Dovecot
by The Doctor 14 Nov '14

14 Nov '14

Got a customer using Evolution 2.12.3 and was using SSL and could not retrieve e-mail in the last week. Got the custome to turn off SSL and he was able to retrieve e-mail. Recently I compiled SSL so that any comprimise was removed and then all apps using SSL including dovecot was recompiled. Could this be an app/Evolution issue? -- Member - Liberal International This is doctor@@nl2k.ab.ca Ici doctor@@nl2k.ab.ca God,Queen and country!Never Satan President Republic!Beware AntiChrist rising! http://www.fullyfollow.me/rootnl2k Look at Psalms 14 and 53 on Atheism Lest we forget 2014

Dovecot wiki LMTP description
by Ron Leach 14 Nov '14

14 Nov '14

List, we are planning a new configuration to which we'll migrate an existing installation shortly. We are hoping to use Dovecot LMTP and have a query about the wiki entry for LMTP http://wiki2.dovecot.org/LMTP where it suggests this config: service lmtp { inet_listener lmtp { address = 192.168.0.24 127.0.0.1 ::1 port = 24 } Does this example mean that LMTP will only listen for input messages from the interface with IP address 192.168.0.24 (plus localhost)? If so, I probably haven't understood how LMTP is intended to work. Is there a reason why we want to limit LMTP to listening for messages from a specific IP on the network? I need to understand that so that I replace ...24 with a suitable host interface that exists on our LAN (we don't have a host at 192.168.0.24). Apologies for what must seem, to people using LMTP, a very basic question. Nevertheless, I would be grateful for any clarification. regards, Ron

Dovecot Cur and New Directories are empty
by Nguyen Dinh Phuoc Thanh 14 Nov '14

Hi, Recently, we faced an issue with dovecot. Mail delivered to New directory, but after we used Outlook to connect with POP3 protocol, there was no email delivered to Outlook and New/Cur directory was empty.

automatically create Spam mailbox
by Cliff Hayes 14 Nov '14

14 Nov '14

I am trying to set up dovecot to automatically create a Spam mailbox for every user. http://wiki2.dovecot.org/MailboxSettings shows how to do this but not what config file to put it in so I assume 10-mail.conf. When I put it in there as follows... namespace inbox { mailbox Spam { auto = create special_use = \Junk } } ... I get the following error ... doveconf: Fatal: Error in configuration file /etc/dovecot/conf.d/10-mail.conf line 107: Unknown setting: mailbox How do I create the mailbox?

Core Dump upon startup (SEGV) - v2.2.10

In my recent messages I mentioned how I was having difficuilty in making my wife's email readable in Squirrelmail; this was solved with directory permissions. However, my usual email client is Thunderbird; I was holding off on using that as there appeared to be authentication issues. Today was my opportunity to start debugging those; it occurred to me that I might have issues with PKI and tried to make/install working certificates. When this didn't work, I though to just scrub the installation and start over. On my CentOS 7 system I erased and reinstalled from RPM. With what should have been working certificates, I ran through the config files, and then restarted to the following error: [root@dungeon dovecot]# systemctl -l status dovecot.service dovecot.service - Dovecot IMAP/POP3 email server Loaded: loaded (/usr/lib/systemd/system/dovecot.service; disabled) Active: failed (Result: core-dump) since Thu 2014-11-13 19:05:52 EST; 30min ago Process: 23700 ExecStart=/usr/sbin/dovecot -F (code=dumped, signal=SEGV) Process: 23695 ExecStartPre=/usr/libexec/dovecot/prestartscript (code=exited, status=0/SUCCESS) Main PID: 23700 (code=dumped, signal=SEGV) Nov 13 19:05:52 dungeon.the-leveys.us systemd[1]: Started Dovecot IMAP/POP3 email server.
