I have configured a mail server with the help of this tutorial and it was working fine till I add a new user to mail database. first there was Maildir problem for that user only (with sending an email to the new user, it wasn't solved, and I solved it by creating directories manually) but now all users have some problems: first of all when I try to login via squirrelmail, I get the following in mail.log: Code: Oct 2 00:23:31 www imaplogin: Connection, ip=[::ffff:127.0.0.1] Oct 2 00:23:31 www imaplogin: LOGIN, [email protected], ip=[::ffff:127.0.0.1], protocol=IMAP Oct 2 00:23:31 www imaplogin: LOGOUT, [email protected], ip=[::ffff:127.0.0.1], headers=0, body=0, time=0 and similary with thnderbird: Code: Oct 2 02:07:35 www courierpop3login: Connection, ip=[::ffff:my_ip_address] Oct 2 02:07:36 www courierpop3login: LOGIN, [email protected], ip=[::ffff:my_ip_address] Oct 2 02:07:36 www courierpop3login: LOGOUT, [email protected], ip=[::ffff:my_ip_address], top=0, retr=0, time=0 Oct 2 02:07:36 www courierpop3login: Connection, ip=[::ffff:my_ip_address] and I think the reason of others also is this only! I have searched a lot but I couldn't find the solution. and one more question: Is there any easier way to add new user except adding to bank.
