I have setup a postfix mail server with saslauthd. I telnet from a windows machine to send a mail. All works fine, I even get the msg 250 Mail queued for delivery. On the mailserver I see connect msgs on /var/log/mail.log for connection but not for the mail queuing or delivery. Only after I close the telnet connection I get all the valid msgs in mail.log. The mail also doesnt arrive in my Maildir/new directory until I close the connection. I am very new to Ubuntu, any pointers will be much appreciated. Many thanks.
