[Bug 503008] Re: Dovecot-auth doesn't close sockets

[Gaylord Holder]

Chuck,

Sorry for the delay replying to this.

I finally tried your suggestion, setting:
auth_worker_max_request_count = 10
in dovecot.conf.

I get the following on restart:

* Restarting IMAP/POP3 mail server dovecot 
        Error: Error in configuration file /etc/dovecot/dovecot.conf 
line 650: Unknown setting: worker_max_request_count
Fatal: Invalid configuration in /etc/dovecot/dovecot.conf

dpkg shows:

ii  dovecot-imapd                         1:1.0.10-1ubuntu5.2 
             secure IMAP server that supports mbox and maildir mailboxes

Any ideas?
