[Dovecot] Password scheme module thoughts?
by Ian R. Justman 11 Oct '08

11 Oct '08

Hi, all. I have successfully deployed the code I wrote to handle Post.Office password hashes. However, I had to implement it as a hack to password-scheme.c. I'd like to implement it as a module so I don't have to hack Dovecot whenever a new release comes out. However, I had a few thoughts: 1. I used Dovecot's own MD5 routines in my implementation because I know how they behave. However, would it make sense to distribute the C sources for the MD5 routines, or would it make far more sense to have a Dovecot build tree already (so I can use Dovecot's function library)? 2. Is there good documentation for Dovecot's plugin API? I need it so I can figure out how to write the parts which the main program call so then the code can be used as a plugin. Thanks! --Ian. -- Ian R. Justman UNIX hacker. Anime fan. Any questions? ianj (at) ian-justman.com

[Dovecot] sieve multi-line parser bug
by info 10 Oct '08

10 Oct '08

Dear sirs Thank you and congratulations for creating Dovecot. When a message header is split along several lines, it seems only the first one is parsed by sieve. The following header: From: "=?iso-8859-1?Q?Cotiatododia=20-=20O=20Jornal=20de=20Not=EDcias=20a=20Se?= =?iso-8859-1?Q?rvi=E7o=20de=20Cotia=20e=20Regi=E3o=2E?=" <newsletter(a)cotiatododia.com.br> was not discarded by the following rule (when it should have been due to "cotiatododia"): if anyof (header :contains ["From", "Reply-To", "To", "Cc"] ["cotiatododia", "ganhedinheiro.com", "1000deaths.com", "ione.correia", "nsbezerra", "estudenoexterior.com", "pestana(a)mauriciopestana.com.br", "institutojairmoura2(a)gmail.com", "webmaster(a)ie.org.br", "jahgor(a)jahgor.com.br", "marketing(a)mirostur.com.br"], header :contains "Subject" "E ai!, Essa voce Tem que Ver!") { discard; } Thank you, Dennis

[Dovecot] Switching Servers now can't retrieve mail
by lists＠kesh.com 10 Oct '08

10 Oct '08

I have just switched my mail server. I have copied (I think) the config files from the old to new. Exim is work fine on the new machine as I can see email file showing up in /var/mail/lists/new . However, dovecot reports nothing when I check mail . I am have turn on logging on both machines and I do not see anything that looks like an error. I have also looked to see if the dovecot.conf file is compatible between 1.0.14 and 1.1.2 and have found little. I am guessing this is a simple problem, can someone tell me what I have done wrong here. I have provided Working dovecot -n from both machines and the log output from a mail fetch.

[Dovecot] Cyrus MailDir to Dovecot mbox
by CJ Keist 10 Oct '08

10 Oct '08

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Anyone out there know of a tool that can convert a Cyrus MailDir format to Dovecot mbox? I have a user that I need to move over from a mail server running cyrus using MailDir format. At first I told him to setup second account with Thunderbird to our mail server and then use Thunderbird to move the messages over. But he has over 100K messages so not as easy to do. Is there a tool out there for doing this sort of conversion? I tried to simply cat all the messages into a single file, but just got a "Not valid mbox format" when I tried to read the mail folder. - -- C. J.

[Dovecot] Test environment question
by Stewart Dean 09 Oct '08

09 Oct '08

My production DC machine owns the mail filesystems and is running DC V1.0.15 and mbox folder format. I am looking to test V1.1.3 on another machine, which NFS mounts the mail filesystems, but has its own local index FS. I have made this test environment my default connection in TBird, and it seems to work just fine. Also, I have made sure that my TBird client isn't connecting to the production server (it has multiple accounts but I have turned off the cehck for mail when starting and check for new mail every N minutes functions, and then check the ps table to make sure there are no imap connections) However, I'm seeing two errmsgs in the maillog on the test machine: > Sep 22 11:54:13 egg mail:err|error dovecot: IMAP(sdean): posix_fallocate() faile > d: Protocol not available > Sep 22 11:54:13 egg mail:err|error dovecot: IMAP(sdean): file_set_size() failed > with mbox file /var/spool/mail/sdean: Protocol not available which appear to happen AFTER mail arrives at the production server....it seems to happen on my test server the next time my client goes to access mail AFTER mail has arrived at the production server. Subsequent client requests of the test server execute without error until AFTER the next time mail arrives at and my inbox is updated with it. Again, if I hadn't looked at the logs, I wouldn't know there was a problem...I can see my new mail just fine from the test server. The questions: Is this anything I should be concerned about? Is this a bug or a legit problem coming from my improper use of two servers against the same data. FWIW, I am using fcntl for both mbox read and write locks. procmail in the MDA on the production server, and its locking hierarchy <dotlock,fcntl>, which Timo previously approved. Thanks!

[Dovecot] shared mailboxes in 1.2 question
by Robert Schetterer 09 Oct '08

09 Oct '08

Hi Timo, i tried a littel bit playing with shared mailboxes namespace shared { separator = / # %%u gets expanded to the remote user. Instead of %%u you can # also use %%n and %%d. prefix = "shared/" location = maildir:/usr/local/virtual/%d:CONTROL=/usr/local/virtual/%d:INDEX=/usr/local/virtual/%d inbox = no list = yes subscriptions = yes hidden = no } should at last show all other users mailboxes when .DEFAULT acl is authenticated lr and dovecot-acl in /usr/local/virtual/%d is authenticated lr too but instead only shared is shown in thunderbird playing with %%u etc in combinations does not lead to working results too (sometimes shared^^ was shown, might be user(a)domain.de isnt working for shared maildirs, @ could be a problem to maildir....?) your example was namespace shared { separator = / # %%u gets expanded to the remote user. Instead of %%u you can # also use %%n and %%d. prefix = shared/%%u/ location = Maildir:/home/%%u/Maildir:INDEX=~/Maildir/shared/%%u } so something with acl might not working in 1.2 and i think i need more explanation ( examples ...) in using %%u %%d ... to test shared mailboxes there were no usefull log entries which would give some more advice during testing...so it might be my fault and it only config stuff i didnt understand -- Best Regards MfG Robert Schetterer Germany/Munich/Bavaria

[Dovecot] Maildir size report for imap?
by Mark Zealey 09 Oct '08

09 Oct '08

Hi guys, It would be really nice if there were an easy way to see how much space an individual imap account used when a user logged out; something like pop3_logout_format = size=%s. I appreciate that this isn't so easy in imap though - I was thinking of using the quota plugin with no limit or something like that.
