[Dovecot] Dovecot with iPhone
by Erik Dasque 05 Jul '07

05 Jul '07

Hi, anyone using their Dovecot server with an iPhone ? While the iPhone is able to see the Inbox, I can't get it to see the other folder. I have tried ~/Maildir, /home/ed/Maildir and Maildir as the IMAP prefix but to no avail. Anything I am overlooking ? Erik

[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

Re: [Dovecot] Permission errors when creating/reading files in users' mail directories

Removing the spurious /etc/passwd entry (and fixing the local file ownerships) gets rid of the permission problems. Thanks for your help.

[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? Thanks in advance, Bryan -- ======================================================================== Bryan Wright |"If you take cranberries and stew them like Physics Department | applesauce, they taste much more like prunes University of Virginia | than rhubarb does." -- Groucho Charlottesville, VA 22901| (434) 924-7218 | bryan(a)virginia.edu ========================================================================

[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] dotlock O_EXCL query
by derek kit hoong foo 05 Jul '07

05 Jul '07

Hi there, I was wondering if someone can assist with clarifying why O_EXCL does not always work with NFS. Is it related to NFS protocol version support or export permissions mode out of the Celerra/Netapp ( e.g: mixed mode, unix file permissions ? ) Please advise. Thanks. Regards, new dovecot user.

[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. Eventually, auth segfaults: Core was generated by `dovecot-auth'.
