Did you check with auth_debug_passwords=yes what the password is? v1.2 doesn't seem to log it clearly, but by base64 decoding resp= value you could see it.
The "password mismatch" would suggest that Squirrelmail may be having a problem, which I have asked about on their list. However, just to cover my bases, is there something else that could have happened that would be causing dovecot to get *random* password mismatch errors?
I vaguely remember seeing something like this before too .. but I don't remember what the end result was. Maybe you could find something from Dovecot mailing list archives.
