Hi I use dovecot 2.1.5 with postfix, amavis, spamassasin, mysql, virtual domains only. Dovecot being used for SASL authentication, and delivery. When I connect via telnet to port 25 or with smtp and try to do auth plain with mmencode connection string authentication works fine. I can send and recieve messages, and relay works as well.

Trying to set up thunderbird to connect to this server I get problems - seems as if the password is resolved proper from the database (use postfixadmin), but then compares an upper case version of my password in the MD5-CRYPT() call to the password string obtained from the database. I do see the base64 encoded connection string in dovecot log though.

Any ideas?

extract from /var/log/dovecot.log: 345 resp=AHRlc3RAZWF0cmlnaHQtYmVoZWFsdGh5LmNvbQBURVNURVI= 2012-05-09 09:55:03 auth-worker(19577): Debug: sql(test@eatright-behealthy.com,4 1.48.226.1): query: SELECT password FROM mailbox WHERE username = 'test@eatright -behealthy.com' 2012-05-09 09:55:03 auth-worker(19577): Info: sql(test@eatright-behealthy.com,41 .48.226.1): Password mismatch 2012-05-09 09:55:03 auth-worker(19577): Debug: sql(test@eatright-behealthy.com,4 1.48.226.1): MD5-CRYPT(TESTER) != '$1$5224e6b6$bmc53Tpz2h3nknBCq/emc/' 2012-05-09 09:55:05 auth: Debug: client out: FAIL 3 user=test@eatrig ht-behealthy.com 2012-05-09 09:55:05 imap-login: Info: Disconnected (auth failed, 3 attempts in 1 5 secs): user=test@eatright-behealthy.com, method=PLAIN, rip=41.48.226.1, lip= 216.144.nnn.125, TLS 2012-05-09 10:01:52 auth: Debug: Loading modules from directory: /usr/local/lib/ dovecot/auth 2012-05-09 10:01:52 auth: Debug: auth client connected (pid=31830)

The password should be 'tester' - not 'TESTER' dovecot -n output:
