[Dovecot] Tbird-DC state problem
by Stewart Dean 09 Jul '07

09 Jul '07

A experienced sysadmin who's doing some guinea-pig use of DC just ran into the following situation: 1) He brings up SeaMonkey 2) About 30 minutes later, he's in the middle of some involved messaging, mistakenly hits the redX in the top right of the SeaMonkey window, knocking himself out of SeaMonkey. 3) He immediately reinvokes SeaMonkey, all appeared to be OK Viewed some e-mail and some web page references, tries to send a message and then the Send hung for a time with a message "Sending Authenticate Info"..after some minutes, a new E-mail window appeared stating the "Server reported a timeout". As far as the message, it was apparently sent successfully, and saved in the Sent folder successfully. 4) He calls me in. I look through the syslog logging. There is nothing in the syslog critical stuff...and everything in the maillog looks normal. 5) He starts another message, tries to save it to Drafts and that hangs 6) I look more closely at the maillog and see a lot of logins (one a minute in some cases, but all appear to have been cleanly executed) plus one bunch of disconnected messages with one disconnected in idle in the period when the write to the Drafts would have been hung. Could it be that DC was in the middle of clean up in the initial disconnect/reconnect and SeaMonkey came back in the middle of it and one or the other's state tables got messed up (or both of them)? Shutting out of SeaMonkey, waiting a minute and reconnecting seems to have gotten things working again. Any comments? Anything I should be looking for? OTOH, this is the first real problem I've seen in some person-months of testing..... -- ==== Stewart Dean, Unix System Admin, Henderson Computer Resources Center of Bard College, Annandale-on-Hudson, New York 12504 sdean(a)bard.edu voice: 845-758-7475, fax: 845-758-7035

[Dovecot] PHP implementation of dovecotpw passwords
by Frank Church 09 Jul '07

09 Jul '07

I am looking for PHP functions that implement passwords that much the dovecotpw implementation. I downloaded one from PEAR, Crypt_HMAC, but the passwords it generates look nothing like the dovecotpw passwords, which could be my fault because I know nothing about the field. Is there a guide or some library that implements them to match dovecotpw?

[Dovecot] Your IMAP server has closed the connection.
by Dehnert James Sr 09 Jul '07

09 Jul '07

I'm getting a large number of ... "Your IMAP server has closed the connection. This may occur if you have left the connection idle for too long." errors. These are confusing my clients. Is there a way to set the timeout on the dovecot server to help avoid this?

[Dovecot] Virtual servers
by John Hedges 06 Jul '07

06 Jul '07

Hello I'm migrating from Courier to Dovecot (1.0.rc15) on Debian. I am trying to set up virtual servers based on the principal in this thread: http://www.dovecot.org/list/dovecot/2006-October/017165.html which suggests something like this to support multiple certificates: server foo { listen = 1.2.3.4 ssl_cert_file = /etc/ssl/certs/foo.cer } server bar { listen = 1.2.3.5 ssl_cert_file = /etc/ssl/certs/bar.cer } My virtual configs look like this: server mail.domain1.org { listen = 1.2.3.4 protocols = pop3 pop3s imap imaps ssl_cert_file = /etc/mail/hosts/domain1.org/ssl.crt ssl_key_file = /etc/mail/hosts/domain1.org/ssl.key auth default { mechanisms = plain passdb passwd-file { args = /etc/mail/hosts/domain1.org/userdb } userdb passwd-file { args = /etc/mail/hosts/domain1.org/userdb } } } server mail.domain2.org { listen = 1.2.3.5 protocols = imap imaps ssl_cert_file = /etc/mail/hosts/domain2.org/ssl.crt ssl_key_file = /etc/mail/hosts/domain2.org/ssl.key auth default { mechanisms = plain passdb passwd-file { args = /etc/mail/hosts/domain2.org/userdb } userdb passwd-file { args = /etc/mail/hosts/domain2.org/userdb } } } but I can't get ithis to work. Dovecot starts but authorisation fails. Is this kind of setup possible - is it possible to configure different passwd-files for connections on different IPs, or am I going to have to run separate instances of Dovecot for each virtual host? Thanks John

[Dovecot] Index question
by Stewart Dean 05 Jul '07

05 Jul '07

The day I switch our user to dovecot and it goes into production, there will be a few thousand people all generating their indices for the first time (we have a legacy requirement for procmail, at least for now), so I wondered: 1) Is there is anyway to pre-emptively force indexing? 2) Is there any value in doing so? That is, will I gain much in terms of making the first time everyone connects to dovecot quicker (not that big initial wait)? -- ==== Stewart Dean, Unix System Admin, Henderson Computer Resources Center of Bard College, Annandale-on-Hudson, New York 12504 sdean(a)bard.edu voice: 845-758-7475, fax: 845-758-7035

[Dovecot] Permission errors when creating/reading files in users' mail directories
by Bryan Wright 05 Jul '07

05 Jul '07

Hi folks, I'm trying to migrate an old uw-imap server to dovecot, and running into puzzling (to me) permission problems. I've configured mail_location as follows: mail_location = mbox:~/mail:INBOX=/var/spool/mail/%u and each user's mail directory has permissions like this: drwx------ 2 uid gid 4096 Jul 5 09:26 /home/uid/mail But when I try to check a user's mail using an imap client, I see the following error: Jul 5 09:59:49 imap dovecot: IMAP(uid): mkdir_parents(/home/uid/mail/.imap/ INBOX) failed: Permission denied If I open up the permissions so anyone can write, I find that the .imap directory is successfully created, and owned by "uid". Is dovecot initially creating the directory with some other ownership, and then changing the ownership to "uid"? I can get around this problem by setting INDEX in mail_location, and pointing it to a directory with more open permissions, but then I run into the next problem: Jul 5 09:25:49 imap dovecot: IMAP(uid): open() failed with mbox file /var/spool/mail/uid: Permission denied In this case, the permissions are set as follows: -rw------- 1 bkw1a mail 1267 Jul 5 08:47 /var/spool/mail/uid How should the permissions be set on the spool files?

[Dovecot] dovecot.conf pop3_uidl_format
by Peter Eriksson 05 Jul '07

05 Jul '07

From the Dovecot 1.0.1 sample dovecot.conf file: # If you want UIDL compatibility with other POP3 servers, use: # UW's ipop3d : %08Xv%08Xu ... # Note that Outlook 2003 seems to have problems with %v.%u format which was # Dovecot's default, so if you're building a new server it would be a good # idea to change this. %08Xu%08Xv should be pretty fail-safe. # # NOTE: Nowadays this is required to be set explicitly, since the old # default was bad but it couldn't be changed without breaking existing # installations. %08Xu%08Xv will be the new default, so use it for new # installations. # pop3_uidl_format = %08Xu%08Xv Notice the *very* small difference in the format between UW's ipop3d and the ones mentioned a little bit below? I think I just got bitten by this (we moved from UW's ipop3d to Dovecot). Loooots of users just got a lot of new (old) mail again ("Leave mail on server" is a popular setting). Ah well. They really should move to IMAP anyway and now they got some summer reading to do :-) Is the difference intentional? If so then perhaps this should be more clearly pointed out! - Peter

[Dovecot] PAM timed out, kill failed, auth SEGV
by Thomas Arnett 04 Jul '07

04 Jul '07

My log is full of blocks like this: auth(default): pam(?): PAM child process 13576 timed out, killing it auth(default): PAM: kill(13576) failed: No such process Often, this is recorded for several pids at once. Occasionally, there's a single burst when a virtual user logs in, immediately before pam_authenticate() fails and checkpassword is executed. When this happens, pam() contains the username and remote IP. Usually, it starts 2 minutes after a login attempt (successful or not) and repeats every 10 seconds indefinitely. pam() contains something else: ~87% ? ~ 9% [garbage],master ~ 4% ?,master < 1% [empty] [garbage] varies; it seems to be constant for an instance of auth, but I haven't verified this.

[Dovecot] Maildir configuration vs ZFS and snapshots...
by Peter Eriksson 04 Jul '07

04 Jul '07

I have a little tricky issue around here. First some background: Every user is assigned their own ZFS filesystem, and it's mounted as /home/USER with a Maildir inside it. The there is a filesystem snapshot (read-only) taken automatically every day by the system. The idea is to allow users easy access to backup copies of their mail so that they can restore things themself.. For example this structure (somewhat abbreviated, some files/dirs removed): /home/testson/ .zfs/ snapshot/ 2007-06-18/ Maildir/ cur/ new/ tmp/ .Trash/ cur/ new/ tmp/ Maildir/ cur/ new/ tmp/ .Trash/ cur/ new/ tmp/ Now,I can access the normal Maildir INBOX and folders nicely via Dovecot/IMAP. The thing is I'd like to be able to access the snapshot too via Dovecot/IMAP somehow. My first idea was to use Dovecots namespace feature like this in the config file: namespace private { separator = / prefix = snapshot/ location = maildir:~/.zfs/snapshot/2007-06-18/Maildir:CONTROL=~/.dovecot/control:INDEX=~/.dovecot/index } This works great for the mail folders inside the Maildir - but not for the INBOX which isn't displayed at all... (Ie, under the "snapshot" prefix I only see "Trash" etc when looking at the folder from an IMAP client). I think that I'd need to use the "INBOX=" option for Dovecot to see the top-level "new/cur/tmp" directories in the snapshot folder, but you can only have one INBOX if I'm not mistaken? Any suggestions on how best to configure this? - Peter

Hi, When an mbox has a filename with a period, the Dovecot 1.0.1 convert plugin will endlessly convert the same mbox causing duplicate messages. To reproduce, create try converting two mboxes: one with a valid name and another with an invalid name. Then, repeat the login procedure a few times. Dovecot should do something more graceful such as replacing periods with another character. Here's /var/log/mail/errors Jul 2 08:29:44 aslan dovecot: IMAP(crystalp): Mailbox conversion: Couldn't create mailbox Print Shop Misc.: Invalid mailbox name Jul 2 08:39:46 aslan dovecot: IMAP(crystalp): Mailbox conversion: Couldn't create mailbox Print Shop Misc.: Invalid mailbox name Jul 2 08:48:54 aslan dovecot: IMAP(crystalp): Mailbox conversion: Couldn't create mailbox Print Shop Misc.: Invalid mailbox name Jul 2 08:48:58 aslan dovecot: IMAP(crystalp): Mailbox conversion: Couldn't create mailbox Print Shop Misc.: Invalid mailbox name Jul 2 08:49:39 aslan dovecot: IMAP(crystalp): Mailbox conversion: Couldn't create mailbox Print Shop Misc.: Invalid mailbox name Jul 2 08:59:40 aslan dovecot: IMAP(crystalp): Mailbox conversion: Couldn't create mailbox Print Shop Misc.: Invalid mailbox name Jul 2 09:09:40 aslan dovecot: IMAP(crystalp): Mailbox conversion: Couldn't create mailbox Print Shop Misc.: Invalid mailbox name Jul 2 09:20:23 aslan dovecot: IMAP(crystalp): Mailbox conversion: Couldn't create mailbox Print Shop Misc.: Invalid mailbox name I didn't test other non-{alphanumeric,whitespace} characters. Other than this and my previous e-mails, our conversion from UW-IMAP mboxes went nicely. I notice the performance difference, and our users will be happy to finally have proper subfolders. Andrew

[Dovecot] listen parm questions
by Stewart Dean 03 Jul '07

Q1: My imap server has 4 interfaces, but only one is used for imap traffic. Can I do this: listen = 10.20.30.40:10143 (when imap.mycollege.edu is 10.20.30.40) Or is there even any benefit to doing this? Q2: Can I specify more than one port....during test eval, I've had the IT dept using port 1043 for listen....which I will, of course, change to 143 when DC goes production. So my department isn't cut off by that switchover, can I do this? listen = *:10143,143 or this listen = 10.20.30.40:10143,143 I did look at the wiki but didn't see anything -- ==== Stewart Dean, Unix System Admin, Henderson Computer Resources Center of Bard College, Annandale-on-Hudson, New York 12504 sdean(a)bard.edu voice: 845-758-7475, fax: 845-758-7035

[Dovecot] [Fwd: Bounce action notification]
by Timo Sirainen 03 Jul '07

03 Jul '07

Anyone have ideas why this happened? Nothing special in logs, all tss(a)iki.fi deliveries went OK. Mailman's bounce log is unhelpful. Why does it say it tried to deliver to dovecot(a)dovecot.org and when it failed it disabled my account? Why doesn't it even bother saying which remote host gave an error? Grepping mail.log for 'This user' shows nothing.
