Hi,
I have: auth_cache_size = 4096 auth_cache_ttl = 3600 I use Thunderbird connecting to my Dovecot IMAP server 1.1rc1. I click on five folders and close Thunderbird. This is my log: dovecot: Feb 27 17:26:56 Info: Dovecot v1.1.rc1 starting up dovecot: Feb 27 17:26:56 Info: auth-worker(default): mysql: Connected to auth01 (Auth) dovecot: Feb 27 17:27:07 Info: imap-login: Login: user=<roka-05>, method=PLAIN, rip=10.4.32.70, lip=10.4.32.235 dovecot: Feb 27 17:27:08 Info: imap-login: Login: user=<roka-05>, method=PLAIN, rip=10.4.32.70, lip=10.4.32.235 dovecot: Feb 27 17:27:10 Info: imap-login: Login: user=<roka-05>, method=PLAIN, rip=10.4.32.70, lip=10.4.32.235 dovecot: Feb 27 17:27:11 Info: imap-login: Login: user=<roka-05>, method=PLAIN, rip=10.4.32.70, lip=10.4.32.235 dovecot: Feb 27 17:27:13 Info: imap-login: Login: user=<roka-05>, method=PLAIN, rip=10.4.32.70, lip=10.4.32.235 dovecot: Feb 27 17:27:20 Info: IMAP(roka-05): Disconnected: Logged out bytes=83/469 dovecot: Feb 27 17:27:20 Info: IMAP(roka-05): Disconnected: Logged out bytes=106/524 dovecot: Feb 27 17:27:20 Info: IMAP(roka-05): Disconnected: Logged out bytes=71/463 dovecot: Feb 27 17:27:20 Info: IMAP(roka-05): Disconnected: Logged out bytes=356/4887 dovecot: Feb 27 17:27:20 Info: IMAP(roka-05): Disconnected: Logged out bytes=147/939 In Outlook Express: dovecot: Feb 27 17:27:38 Info: imap-login: Login: user=<roka-05>, method=PLAIN, rip=10.4.32.70, lip=10.4.32.235 dovecot: Feb 27 17:27:38 Info: IMAP(roka-05): Disconnected in IDLE bytes=65/112 dovecot: Feb 27 17:27:38 Info: imap-login: Login: user=<roka-05>, method=PLAIN, rip=10.4.32.70, lip=10.4.32.235 dovecot: Feb 27 17:27:38 Info: IMAP(roka-05): Disconnected in IDLE bytes=259/1098 dovecot: Feb 27 17:27:44 Info: imap-login: Login: user=<roka-05>, method=PLAIN, rip=10.4.32.70, lip=10.4.32.235 dovecot: Feb 27 17:27:51 Info: IMAP(roka-05): Disconnected: Logged out bytes=1682/10349 Sort of the same thing: but more inconsistent. Sometimes I click five folders and OE will have done 3 logins sometimes 2. So new IMAP logins for (more or less) every click in Thunderbird and OE; this is what auth_cache_size should solve right? Am I applying the auth_cache_* variables wrong or is something else wrong? Cheers, Jan
