So all your control files were being recreated, but index files weren't? I guess that confused Dovecot somehow. The error messages probably aren't exactly correct, but you created a broken condition anyway. :) > Last question, what permissions are needed for /var/lib/dovecot/control/ if > it's used as CONTROL= and users use different uid/gids?

There's really no better way since the directories aren't created as root. signature.asc Description: This is a digitally signed message part

Done that and now I see a lot of " Expunged message reappeared, giving a new UID (old uid=10753, file=...)" ugh :-/ I guess now imap clients will see these as new messages? Also ": IMAP(bo): /var/lib/dovecot/control/xxx/.INBOX/dovecot-uidlist: Duplicate file entry at line..." Weird, these are fresly created control files and now they contain duplicates. Last question, what permissions are needed for /var/lib/dovecot/control/ if it's used as CONTROL= and users use different uid/gids? Right now I have a+rwx which doesn't look nice and root:root 660 also didn't make dovecot happy. -- Arkadiusz MiśkiewiczPLD/Linux Team arekm / maven.plhttp://ftp.pld-linux.org/

Yes, changing the CONTROL to non-quota partition is the only way to solve this for now. I suppose it should be possible to have the existing mails visible though, but mails not listed in dovecot-uidlist can't really be made visible. signature.asc Description: This is a digitally signed message part

Are you using v1.0? 1.1.7 as in subject but read-only won't help in deleting mails that cause quota being exceeded 8) -- Arkadiusz MiśkiewiczPLD/Linux Team arekm / maven.plhttp://ftp.pld-linux.org/

I suppose it's not very ideal either if user can't delete mails then, but at least the mailbox doesn't get corrupted. Anyway, you most likely don't really need to use dotlocks at all. Just make sure that your MDA uses fcntl locks and set mbox_write_locks=fcntl. Also I think Dovecot v1.1 should be able to open the mailbox read-only even if it can't create the dotlock? Are you using v1.0? signature.asc Description: This is a digitally signed message part
[Dovecot] 1.1.7: quota problem, unable to delete mails when quota exceeded
Hi, When user exceeds it's quota then dovecot can't create it's files and it's showing zero mails :( This also means that user is unable to delete it's own mails. Sounds like kind-of bug, right? Dec 15 08:28:37 mbox1 dovecot: IMAP(xxx): open(/var/mail/xxx/dovecot-uidlist.lock) failed: Disk quota exceeded Dec 15 08:28:37 mbox1 dovecot: IMAP(kdudus): file_dotlock_create(/var/mail/xxx/dovecot-uidlist) failed: Disk quota exceeded This sometimes ends with: Dec 15 08:36:43 mbox1 dovecot: IMAP(xxx): Disconnected: Internal error occurred.
