[Dovecot] typo caused dovecot-acl line 1: Unknown ACL ' '
by Adam McDougall 02 Mar '08

02 Mar '08

A co-worker edited a dovecot-acl file and accidently introduced a space at the end of a "user=username lrwstie" entry. Fortunately he noticed errors in his own mail client, but I'm not sure what may have happened to other users. Would it be possible to make dovecot more forgiving by ignoring whitespace at the end of ACLS to avoid this issue?

[Dovecot] rmdir() warnings with 1.1.rc1
by Dean Brooks 02 Mar '08

02 Mar '08

Hi, Looks like there are still some Solaris rmdir() warnings being logged to syslog in 1.1.rc1 in nfs_flush_file_handle_cache_dir(): Feb 23 13:09:51 sx3 dovecot: [ID 107833 mail.error] IMAP(ran04): \ nfs_flush_file_handle_cache_dir: rmdir(/var/mail) failed: Device busy Manual for rmdir on Solaris states: EBUSY The directory to be removed is the mount point for a mounted file system. We are using /var/mail mounted from NFS, which explains the EBUSY return code. Not sure how you would be able to get the cache flushed in this situation. -- Dean Brooks dean(a)iglou.com

[Dovecot] nfs locking issues...
by John Gray 01 Mar '08

01 Mar '08

I'm running Dovecot 1.1 RC1. I believe I've done all the due diligence for making things working correctly over nfs. But I run into locking issues if I run over nfs. procmail is doing the delivery over nfs. uw-imap was ruining over nfs. dovecot is fine if its on the nfs server (i.e. it has local access to the disk, no nfs) I run into lock deadlocks if I run dovecot over nfs Users are directed to different servers, but a given users will always get the same server (at least until there's no activity for that user for over an hour). This only applies to when running dovecot over nfs. Everybody goes to the nfs server otherwise. Sometimes I can kill all the processes, remove the dot locks, and recover. Something I need to reboot the nfs server to recover. Let me give a run down of the particulars: All the mail is in mbox format. everybody runs linux with kernel 2.6.24.2 (any known nfs locking issues there?). delivery is done via procmail, its locking and dovecot's are both dotlock, fcntl. The nfs mount options are actimeo=3,hard,noatime,rsize=32768,wsize=32768,nfsvers=3 The clocks are in sync. Dovecot.conf: protocols = imap imaps pop3 pop3s login_greeting = imap ready. mail_location = mbox:~/:INBOX=/var/mail/%u mmap_disable = yes mail_nfs_storage = yes mail_nfs_index = yes protocol imap { } protocol pop3 { pop3_uidl_format = %08Xu%08Xv } auth default { mechanisms = plain passdb pam { } userdb passwd { } user = root } dict { } plugin { } Any help would be greatly appreciated.

01 Mar '08

Hy I use dovecot with quota support. I did a test with a webmail client (roundcube) & quota= 10 M when I have used 100% of the quota assigned to the mail account , I cannot delete any mail Is it possible to create a kind of warning mail about 80% of quota use or overpass quota for delete operations? Thanks

[Dovecot] links causing dovecot endless search through user's homedirs
by Paul Letta 29 Feb '08

29 Feb '08

Hello, My user's imap folder locations are a mess. Some have them in /home/username/mail but a lot of them just have them in /home/username. So I need to have dovecot's base imapdir pointed directly at the user's homedirs. My problem now is that a lot of users have many links in their homedirs. Some even have circular links, such as: /home/username/foo/foo1/foo2/foo3/foo4 -> /home/username/foo/foo1 All these links are causing some dovecot imap process to endlessly search. An example of a strace of a running imap processes shows: stat64("/home/xxx//jlab/jlab/dev/tail/interp/radcor/results/fake/e94010/3RDTRY/interp/radcor/results/fake/e94010/3RDTRY/interp/radcor/resul ts/fake/e94010/3RDTRY/interp/radcor/results/fake/e94010/3RDTRY/interp/radcor/results/fake/e94010/3RDTRY/interp/radcor/results/fake/e94010/3RDT RY/interp/radcor/results/fake/e94010/3RDTRY/interp/radcor/results/fa ... and so on. Since I can't get a hold of my users and make them all put their imap folders in /home/username/mail and configure dovecot to just search there... Is there a way to tell dovecot to ignore links ?
