I've updated my mail server last night, from
Debian etch to lenny. So far I've encountered a problem with my postfix installation, mainly that I managed to broke the IMAP access somehow.
When trying to connect to the IMAP server with Thunderbird, all I get in mail.log is:
Feb 12 11:57:16 mail imapd-ssl: Connection, ip=[::ffff:10.100.200.65]
Feb 12 11:57:16 mail imapd-ssl: LOGIN: ip=[::ffff:10.100.200.65], command=AUTHENTICATE
Feb 12 11:57:16 mail authdaemond: received auth request, service=imap, authtype=login
Feb 12 11:57:16 mail authdaemond: authmysql: trying this module
Feb 12 11:57:16 mail authdaemond: SQL query: SELECT username, password, "", '105', '105', '/var/virtual', maildir, "", name, "" FROM mailbox WHERE username = '
[email protected]' AND (active=1)
Feb 12 11:57:16 mail authdaemond: password matches successfully
Feb 12 11:57:16 mail authdaemond: authmysql: sysusername=<null>, sysuserid=105, sysgroupid=105, homedir=/var/virtual,
[email protected], fullname=<null>, maildir=xoxo.sk/
[email protected]/, quota=<null>, options=<null>
Feb 12 11:57:16 mail authdaemond: Authenticated: sysusername=<null>, sysuserid=105, sysgroupid=105, homedir=/var/virtual,
[email protected], fullname=<null>, maildir=xoxo.sk/
[email protected]/, quota=<null>, options=<null>
...and then Thunderbird proceeds to complain that it cant' login / lost connection. Thunderbird is definitely not configured to connect through SSL/TLS.
POP3 (also provided by Courier) is working fine.
I've been mainly looking for a way to make the courier-imap logging more verbose, like can be seen for example here.
Edit: Sorry about the mess, I've found that I've been funneling the log through grep imap, which naturally didn't display entries for authdaemond.
The verbose logging configuration entry is found in /etc/courier/imapd under DEBUG_LOGIN=1 (set to 1 to enable verbose logging, set to 2 to enable dumping plaintext passwords to logfile. Careful.)
