Hi

We've been using dovecot successufly for few month.

Previous setup : solaris 8, postfix+LDA, mbox + index on NFS (Netapp), 2500 accounts Everything shared overs NFS, multiple servers connect to index, mbox. mail_location = mbox:/var/mail/mbox/%u:INBOX=/var/mail/%u:INDEX=/var/mail/indexes_dovecot/%u We had at first some issue with mbox locking, using lock_method = dotlock solve the issue. The problem seemed to be with fcntl.

I Migrate to maildir to ease administration to use maildir quota I use mb2md-3.20.pl to migrate the mbox everything works smooth.

Actual setup : solaris 8, postfix+LDA, maildir + index + control on NFS (Netapp)

I change the mail_location settings to mail_location = maildir:/var/mail/maildir/%u:INDEX=/var/mail/indexes_dovecot/%u:CONTROL=/var/mail/dovecot_control/%u

And now I'm facing new locking issue :

Errors on user loging, users leaving mail on server downloading the same mail over and over.

Numerous entries in log files :

May 2 11:19:03 gregorie dovecot: [ID 107833 mail.error] POP3(carini): Maildir /var/mail/maildir/carini sync: UID inserted in the middle of mailbox (13 > 1, file = 1178097228.P16222Q0M452645.yder,S=22935:2,) May 2 11:19:03 gregorie dovecot: [ID 107833 mail.info] POP3(carini): Disconnected: Mailbox is in inconsistent state. top=0/0, retr=0/0, del=0/0, s ize=0 May 2 11:19:03 gregorie dovecot: [ID 107833 mail.error] POP3(carini): Couldn't init INBOX: Internal error occurred. Refer to server log for more i nformation. [2007-05-02 11:19:01]

Seems to be locking issue, numerous .nfs files in INDEX & CONTROL location

The maildirsize & dovecot-uidlist files aren't update properly

Does the patch posted here still apply ? http://dovecot.org/list/dovecot/2006-December/018145.html

Is the any
