password FROM vmail WHERE mail = 'test at mail' Info: auth-worker(default): sql(test at mail ,IP): Password mismatch Info: auth-worker(default): sql(test at mail ,IP): SHA1(dupadupa) != '2bca9dbe8a14811c687bb8c51c0e1cd14db8a018' I tried convert password to upper case, but it didn't help. Then I tried authentication in plain text and everything works fine... So, does dovecot crypt SHA1 using other method? I also use same SHA1 passwords to authenticate users in exim and it doesn't have any problem with that. I'm using mysql 5.0.24 and dovecot 1.0 rc7. Best regards, Tomasz Krynicki
