Re: [Dovecot] Problems with the IMAP proxy after upgrading from dovecot 1.1.16 to 1.211
May 7 14:47:42 ttt dovecot: auth(default): worker-server(uid,yyy.yyy.yyy.yyy): Aborted: Lookup timed out May 7 14:47:42 ttt dovecot: auth-worker(default): mysql: Connected to lll.lll.lll.lll (imapauth) Lookup timed out really shouldn't be happening.. That sounds like Dovecot's MySQL connections hangs after a while? You have some stateful firewall between Dovecot and MySQL that drops idling connections and afterwards starts dropping the connection's packets? Indeed, there is a firewall with stateful inspection between Dovecot and MySQL. The only workaround is a downgrade to Dovecot 1.1.20. I think my problem has to do with the changes in src/auth/auth-worker-server.c in changeset 8859.
Re: [Dovecot] Ignoring the quota by the LDA?
Is it possible to configure dovecot in a manner that only the imap
process respects the quota, and the local delivery ignores completely
the quota? I think it should happen if I don't activate the quota
plugin in the lda section but only in the imap section.
Better to override quota setting in protocol lda {} by
adding :noenforcing to it.
Does the :noenforcing parameter work with the maildir quota? It's
documented for the fs quota only. Can I add the parameter direct to
the protocol lda {} section? Does the following construct work?
protocol lda {
...
mail_plugins = quota:noenforcing
...
}

You have some stateful firewall between Dovecot and MySQL that drops idling connections and afterwards starts dropping the connection's packets? Indeed, there is a firewall with stateful inspection between Dovecot and MySQL. Right, so the Lookup timed out works as intended. But I guess it should automatically retry when that happens. There would still be that 1 minute delay before that happens though. The only workaround is a downgrade to Dovecot 1.1.20. Wonder what v1.1 does differently. I can't think of anything, really. The main fundamental problem is still that mysql connection hangs and the hang can't be detected/avoided. I think the right fix here would be to change your firewall settings.. I think my problem has to do with the changes in src/auth/auth-worker-server.c in changeset 8859. 8559:b0bc4519332f? Yep.

Will it work or will it result in a big mess? I've the aim that a mail
will never be rejected because the recipient is over his/her quota.

Re: [Dovecot] INBOX of a shared namespace appears to be always subscribed
There was an other problem. I forgot to remove the .INBOX subdirectories. They were a rudiment of earlier tests. Well, I've removed them, and the original problem is resolved. But now I run into another trouble. The users cannot subscribe to the inboxes other users. The inbox paths in the shared namespace point to the namespace prefixes of the users' shared namespace. And they are marked with the \Noselect flag. Thus the inboxes are unaccessible via the shared namespace. BTW, I've set subscriptions=no in the config file, dovecot -n lists the subscription parameter only if it was set to yes. Holger

What do your namespace settings look like in dovecot -n output?

The LIST * command shows all mailboxes in all namespaces for which the user has the l(ist) permission but the INBOXES of other users are never listed. But the myrights command shows that the ACLs are correct. Holger
Re: [Dovecot] INBOX of a shared namespace appears to be always subscribed
I've repeated the tests with LSUB *. I think there's a problem with setting the namespace prefix. telnet imap.xx.yy 143 1 LOGIN user password 2 LSUB *= shows INBOX Sent Trash folderAA shared/UserB/folderXX 3 LSUB *= shows shared/UserB/INBOX shared/UserB/folderXX Sent Trash folderAA 4 LSUB *= shows shared/UserB/INBOX shared/UserB/folderXX Sent Trash folderAA This behavior is reproducable. Please note that the mailboxes of the shared namespace are listed first and the own inbox of the user disappears. Holger
[Dovecot] INBOX of a shared namespace appears to be always subscribed
In dovecot 1.2.10 I run into the following problem: Our users are entitled to share their personal mailboxes. This works. But if user A shares any of its mailboxes with user B, then dovecot always reports the INBOX of user A as subscribed by user B. No matter whether user B really subscribed the INBOX of A, or whether user A permitted user B the access to its INBOX. The problem is caused by the repeated call of LSUB. Starting with the second call LSUB always shows INBOX as subscribed. To reproduce: - telnet imap.xx.yy 143 1 LOGIN user password 2 LSUB shared/*= shows shared/UserB/folderXX 3 LSUB shared/*= shows shared/UserB/INBOX shared/UserB/folderXX 4 LSUB shared/*= shows shared/UserB/INBOX shared/UserB/folderXX Regards, Holger
