[Dovecot] login BAD Error in IMAP command received by server.

[Yaron B]

hi,

i can open telnet on port 143
but failing on login user/pass and getting -
"login BAD Error in IMAP command received by server."

i assume that i didnt setup properly the authentication method and user/pass
does Dovecot can use postfix user/pass ?

less /var/mail/maillog
