[Dovecot] passwd, gid and uid
by Mauricio Tavares 25 Dec '10

25 Dec '10

I forgot the answer for this: in http://wiki.dovecot.org/AuthDatabase/PasswdFile, we have the passwd file defined as user:password:uid:gid:(gecos):home:(shell):extra_fields What should the uid and gid be associated with? In my setup I told postfix to use Dovecot LDA's deliver, which then is saving files as uid:gid of 1500:1500. How would that affect the uid:gid used in the passwd file? From what I read in the dovecot's wiki, you want them *not* to be anything that has the rights to access the emails. So, does that mean any value for them will do?

[Dovecot] Maildir feature I'd like to see - SSD for newer messages
by Marc Perkel 24 Dec '10

24 Dec '10

SSD drives are very fast but expensive. So I have a crude idea that I'd like to see. May not be practical but would like to get some thoughts on it. Some new SSDs use SATA 3 (6gb/sec) with 355/mb/sec read speeds and 215MB/sec write. Put these in raid 0 and it screams! Can you imagine how fast that would be? What would be nice is if new email were on faster drives with old email being migrated to larger mechanical cheaper storage. Perhaps messages over a month old? From dovecot's perspective it would sort of all look the same but maybe one a week a script would run migrating older messages to slower media. It would also make backups easier. The faster newer messages could be archived hourly. On the weekend after the archiving script was run the older message could be backed up once a week. I'm not sure what it would take to make dovecot seamlessly access email from two different locations or if this is practical. Just wanted to throw the idea out there to see if something sticks.

[Dovecot] Is this an index problem?
by Chris Barnes 23 Dec '10

23 Dec '10

This is my first post to this list/gmane newsgroup, so please be gentle with me.... :-) Here's my situation: I have a user (the "main boss secretary") who uses MS Outlook 2007 as her email client. She has over 46,000 messages in her inbox, with nobody knows how many more in 75+ different folders & subfolders. Surprisingly, her response time wasn't too terrible up until we had to reboot our mail server the other day (actually, restoring the entire server from a backup). Now it takes anywhere from 10 to 60 seconds for her to switch from 1 folder to another. Details: * Server is Debian running Postfix and Dovecot (both the current release). Using Maildir format stored in the user's ~/Maildir folder. * User connects to server via Imaps. Connection is local using gigabit network (ie. it ain't the network). * Yes, we did all the things on the Outlook side -thinking that is where the problem lays. Rebuild the .pst file, had Outlook re-index, compacted the .pst file, etc. So now I'm thinking that maybe I need to just wipe out all of the ~/Mailder/dovecot* files (including all those in sub-directories) and let it all reindex. Which begets 3 questions: (1) will this help? (2) anyone have a shell script that will remove all those dovecot* files from the user's directory AND all the sub-directories? (3) Any other suggestions I might be missing? -- Chris Barnes

[Dovecot] Deliver limit based of number of destination recipients and size of mails, any option to do that?
by Andrés Yacopino 23 Dec '10

23 Dec '10

I have a mail server with postfix, dovecot (1.2.15) and deliver lda (dovecot) with 350 users. I have the problem that in this christmas the employees are sending some big files (mainly powerpoints files) to a lot of recipients, because of that the server get a lot of charge (is a Xeon quad core 5405 with 4GB of Ram), i have four disks in Raid 5 configuration (HP E200 controller, not very fast) Is there any option to limit this type of delivery, the total size of the mails delivered to each user (total recipients * size of mail), in dovecot deliver. I don't want to limit the concurrent delivery more lower than 350 recipients and the max size of the mail we can send is 15M. Thanks a lot, -- Andrés Fernando Yacopino

[Dovecot] trying to make cmusieve happen globally
by Phil Howard 22 Dec '10

22 Dec '10

In Dovecot 1.1.11 cmusieve is apparently integrated in the Ubuntu 9.10 package "dovecot-common" since the files are there. I am wanting to right now just do a very basic test of the setup to see how it runs before doing more sophisticated steps that could obscure any errors or bugs (e.g. unit testing). So I took the following example sieve script from the wiki1 documentation: require "fileinto"; if header :contains "X-Spam-Flag" "YES" { fileinto "spam"; } and recoded it to skip the test and just always do the fileinto step like so: require "fileinto"; fileinto "spamtest"; Then I configured my dovecot.conf file (via dovecot-postfix.conf it really points to) by setting: protocol lda { ... mail_plugins = cmusieve mail_plugin_dir = /usr/lib/dovecot/modules/lda ... } and: plugin { sieve_global_path = /etc/dovecot/sieve-global.d/spam.sieve } I manually compiled /etc/dovecot/sieve-global.d/spam.sieve so there also exists /etc/dovecot/sieve-global.d/spam.sievec in the same directory. Then I restarted both Dovecot and Postfix. Mail is being delivered, but still only to the same place it always has. The filesystem shows these sieve files are not being accessed at all. I've read documents http://wiki1.dovecot.org/LDA/Sieve and http://wiki1.dovecot.org/LDA/Sieve/CMU to come up with this. But it just doesn't seem to be happening. So I guess it is a good thing I've broken my testing down into smaller units. Anything standout that I misinterpreted about the documentation? If not, I can post the whole config files (in case there is a conflict with something else I have done). FYI, I'm only trying to do a global sieve, not per-user sieve scripts. I'll tackle per-user stuff at a later date, after the global is working. -- sHiFt HaPpEnS!

[Dovecot] Per user quota on MySQL

The Tbird add-on as protocol logging facility, so you could check that to find out where it hangs exactly.

[Dovecot] Managesieve with multiple uid's
by Joseba Torre 22 Dec '10

22 Dec '10

Hi, I'm trying to setup a system with dovecot to remove the old courier one, and everything (pop3, imap, lmtp, quotas) but managesieve is working fine. It seems like it's a problem with each user having a separate uid, because I have a working similar setup with a single uid working without problems. In this system when I try to connect to the managesieve port using telnet I get no response: $ telnet localhost 4190 Trying 127.0.0.1... Connected to localhost.localdomain (127.0.0.1). Escape character is '^]'. ^] telnet> quit In the logs I see: Dec 21 14:16:30 v000148 dovecot: managesieve-login: Disconnected: Inactivity (no auth attempts): rip=10.0.4.25, lip=10.0.82.8 Dec 21 14:16:30 v000148 dovecot: managesieve-login: Error: auth: connect(login) in directory / failed: Permission denied (euid=102(<unknown>) egid=103(<unknown>) missing +x perm: /, euid is not dir owner) Dec 21 14:16:30 v000148 dovecot: managesieve-login: Error: auth: connect(login) in directory / failed: Permission denied (euid=102(<unknown>) egid=103(<unknown>) missing +x perm: /, euid is not dir owner) Dec 21 14:19:30 v000148 dovecot: managesieve-login: Disconnected: Inactivity (no auth attempts): rip=10.0.4.25, lip=10.0.82.

[Dovecot] Restarting dovecot-auth stops authentication
by Attila Nagy 22 Dec '10

22 Dec '10

Hi, The Dovecot wiki states that Dovecot's master restarts all died processes, which is good for availability. But when I kill dovecot/auth (to simulate an error condition which happened on a machine), the authentication fails with: Nov 16 14:32:40 be dovecot: imap: Error: net_connect_unix(auth-master) failed: No such file or directory It seems -albeit it gets restarted- dovecot/auth doesn't re-create its socket file. Before: # ls /var/run/dovecot/ anvil auth-worker doveadm-server anvil-auth-penalty config dovecot.conf auth-client dict empty auth-login director-admin lmtp auth-master director-userdb login auth-userdb dns-client master.pid # ps auwx | grep dovecot/auth dovecot 87455 0.0 0.0 20024 3832 ?? S 2:34PM 0:00.01 dovecot/auth # rm /var/run/dovecot/auth-master; kill 87455 # ps auwx | grep dovecot/auth dovecot 88815 0.0 0.0 20024 3776 ?? S 2:36PM 0:00.01 dovecot/auth # ls /var/run/dovecot/ anvil config dovecot.conf anvil-auth-penalty dict empty auth-client director-admin lmtp auth-login director-userdb login auth-userdb dns-client master.pid auth-worker doveadm-server I've deleted the auth-master socket because if I don't, you can't see that it's not re-created. :) Is this a normal behaviour? I understand that killing dovecot/auth is not, but Dovecot could survive this easily, if recreating and re-using the new socket file would work. And loosing dovecot/auth happens sometimes (I don't yet now why). Thanks,
