I can receive mail fine. But now I cannot send mail. I am getting the following error in outlook: Te Server responded: 421 cannot connect to SMT Now I do have it setup in outlook in the outgoing Server My outgoing needs auto. P.S. in roundcube it works fine. Thank you in advance.
Are you abe to connect to your mail account with webmail? If yes, please send a email to the same address that you used to login to webmail and check a minute later if the email arrived in the webmail account.
Ok, so the basic mail setup and configuration of the mailbox is working. Please run the test script from here; http://www.howtoforge.com/forums/showthread.php?t=58408 and post the output. you might also want to check the dns server of the domain at www.intodns.com. especially check that the mx record points to the correct server.

Ok, the postfix mailserver is listening on all interfaces: [anywhere]:25 (18289/master) which is good and port 25 is not blocked in the local firewall of the server. So only the following options remain: 1) there is a firewall or router in front of this server which blocks port 25 2) The server is installed at home or in a offoce and not in a datacenter and the ISP that provides the internet connection blocks port 25 3) The MX record / A-Record for the MX record of the domain points to a wrong server.
