Hello guys! I have Dovecot server (version: 2.2.9) with quota and imap_quota plugins. I wanna know how to get information about quota used of current email.

Query regarding migration from Maillenium to Dovecot mail server
by Sirisha R 29 Dec '15

29 Dec '15

Hi, We have few queries regarding dovecot mail server. Our application used to supported maillenium mail server, but soon this server is going to retire. So we are planning to migrate our application mail server to dovecot for which we seek your help. Previously, the mailboxes that our application used to support were under att domain, then the mailboxes were migrated to maillenium mail server, and aliases of the existing att mailboxes were created by maillenium support group, so that any mail sent to the att mailbox automatically gets redirected to maillenium alias mailbox. For instance, for the mailbox abc.att.com, an alias was created as abc(a)maillenium.att.com<mailto:abc@maillenium.att.com>. Maillenium support group provided us mailServerHost, mailServerUsername and mailServerPassword. We seek your help in migrating from Maillenium mail system to Dovecot.

Hi, I have just updated from Ubuntu 15.04 to 15.10. Unfortunately, sieve scripts are not recognized anymore. Here is my version: > dovecot --version > 2.2.18 > apt-cache policy dovecot-sieve > dovecot-sieve: > Installed: 1:2.2.18-2ubuntu2 > Candidate: 1:2.2.18-2ubuntu2 > Version table: > *** 1:2.2.18-2ubuntu2 0 > 500 http://us.archive.ubuntu.com/ubuntu/ wily/main amd64 Packages > 100 /var/lib/dpkg/status And this is the log entry: > Dec 25 09:24:12 home-le dovecot: lda(user1): Warning: sieve: file > storage: Active sieve script symlink /home/user1/.dovecot.sieve is > broken: Invalid/unknown path to storage (points to /home/user1/sieve). > Dec 25 09:24:12 home-le dovecot: lda(user1): > msgid=<567CFD2C.7070301(a)example.org>: saved mail to INBOX > Dec 25 09:24:12 home-le postfix/local[28536]: 70876BD035A: > to=<user1(a)example.org>, relay=local, delay=0.07, > delays=0.02/0.01/0/0.04, dsn=2.0.0, status=sent (delivered to command: > /usr/lib/dovecot/deliver -c /etc/dovecot/dovecot.conf -m "${EXTENSION}") It is not a permission issue (though there should even be one with more restrictive permissions) > otheruser@home-le:~$ cat /home/user1/.dovecot.sieve > require ["variables","date", "include"]; > > include :personal "00-delete"; > include :personal "01-spam"; > include :personal "50-bulk_filter"; It is apparently also not a path normalization issue (also according to the correct "points to" path in the log).

Debug Dovecot Plugin (shared library)
by David Becher 24 Dec '15

24 Dec '15

Hey! I was just wondering what would be the best way to debug a plugin I am currently writing for dovecot. The plugin basically registers a new IMAP capability and I want to set a breakpoint to the "cmd_handle_new_capability" function (thats just a function name for better explaining purposes). Right now I have opened a connection via openssl ('openssl s_client -connect example:143 -starttls imap') to be able to mess around with the my server. Then I am able to login into the server via 'a login "username" "password"' and feed the server with my self created IMAP capability command. I know that I can start gdb and attach to an already running process via its PID. But how do I know which process I have to attach to? Looking at the output of 'top' it seems to be an instance of the 'imap' command PID USER PR NI VIRT RES SHR S %CPU %MEM TIME+ COMMAND 13413 vmail 20 0 21004 1844 1524 S 0.0 0.0 0:00.00 Iman But its only started the exact moment I issue my IMAP command towards the server, so of course I am not fast enough to track down the PID before the function has returned, so the process handling the command seems to be up only for the short period of time to handle the command, there is no process before which I can attach to. My current workaround is that I put a tail onto /var/log/mail.log and from within my shared library function (cmd_handle_new_capability) I log the PID of the current process, then sleep(10) for 10 seconds, which gives me enough time to have a look at mail.log to get to know the PID which I then can attach to. But isn't there a better way to do this? Maybe attach to the process which originally creates the new process handling the IMAP command and then stepping into it? I hope someone can help me out :) All the best, David

Dovecot 2.2.20 autoexpunge
by Robert Blayzor 23 Dec '15

23 Dec '15

I have configured autoexpunge on some folders: namespace inbox { inbox = yes location = mailbox Junk { auto = subscribe autoexpunge = 30 days special_use = \Junk } mailbox Trash { auto = subscribe autoexpunge = 2 weeks special_use = \Trash } prefix = separator = / } After adding these and restarting, logging in and out several times, I still see messages days/weeks past the autoexpunge setting. I checked the logs but never see any autoexpunge messages logged. Is there something else that needs to be set to trigger this? -- Robert inoc.net!rblayzor XMPP: rblayzor.AT.inoc.net PGP Key: 78BEDCE1 @ pgp.mit.edu

My end goal is a directory structure like the following. I obtained this example by emptying /srv/mail, changing `location = maildir:/srv/mail/' to use mdbox, and then delivering some messages into Public/Alpha and Public/Mike: > /srv/mail/ > ├── dovecot-uidvalidity > ├── dovecot-uidvalidity.567915fa > ├── mailboxes > │ ├── Alpha > │ │ └── dbox-Mails > │ │ ├── dovecot.index.cache > │ │ └── dovecot.index.log > │ ├── dbox-Mails > │ │ └── dovecot.index.log > │ └── Mike > │ └── dbox-Mails > │ ├── dovecot.index.cache > │ └── dovecot.index.log > └── storage > ├── dovecot.map.index.log > └── m.1 I know that dsync can be used to convert between mailbox formats, but is this possible in conjunction with namespaces? I can convert one of my mailboxes to an arbitrary mdbox location on disk using... > dsync -o mail_location=mdbox:/tmp/dbox/ mirror maildir:/srv/mail/.Mike/ ... although this puts the messages inside an INBOX mailbox: > /tmp/dbox/ > ├── mailboxes > │ └── INBOX > │ └── dbox-Mails > │ ├── dovecot.index.cache > │ └── dovecot.index.log > └── storage > ├── dovecot.map.index.log > └── m.1 I could run this once per public mailbox, writing each to a different mdbox location, but am unaware of a method to merge them such that they would work with my Public/ namespace. Is it possible to use dsync to convert my public Maildir mailboxes to mdbox, resulting in my desired directory structure above? I think I want to be able to tell dsync the location as a mailbox name, rather than a disk location, although this doesn't appear to be possible. If not, is there another solution? My best idea at the moment is to make the configuration change and then re-deliver all messages by mailbox name.
