Hello out there,

im running Dovecot on "ubuntu Dapper" serving pop3 only in maildir-style, but the dove-auth-process refuses "answers" to the deliver or login-process from time to time, (several times a day), and I have no glue whats going on and why ... Debbugging password-Auth surprised me, as the transmitted password IS correct and allows an successfull authenification lots of hundreds times a day.... but suddenly runs into trouble ..

here the logs ... (please take care..., I´m a newbie ;-)
