    Hi,

    My smtp server dont't send mail correctly.
    I get mail back and it says:

    Recipient address rejected: User unknown in virtual mailbox table (in reply to RCPT TO command)

    I got the mail back when i followed this page: http://pingability.com/smtptest.jsp it should send the mail succesfully to a mail adres from pingability.com

    Someone who knows the solution?

    Thank you

    Please test your server with a locally installed webmail client instead by sending a email from a local account on the server to itself and take a look at the mail log file if you get any errors.

    In the webmail sending emails went good but when i do external smtp via Outlook or something else it goes wrong, i get the error when sending mail that says "The smtp server dont accept this smtp connection"

    Please post the exact error message from the mail log that appears when the smtp connection is rejected.

    Are you sure that you're connecting to the correct server in Outlook? Have you tried the server's IP instead of a hostname in Outlook?

    Yes because when i do the telnet option it doesnt work, but when i do telnet on imap port 143 then it goes goed

    What's the output of
    Code:
    netstat -tap
    ?
    Is the server hosted in a data center, or do you host it at home or in your office?

    The mailserver is listening on port 25, so that ok. Please post the output of:

    iptables -L

    also make sure that your internet access provider does not block port 25.

    Looks good.

    Is your server located in a datacenter or do you use a dsl or cable line for hosting it?

    Ok. postfix is listening on all interfaces.

    Please restart postfix and amavisd and then look again into the error log if any erors have been added when the daemons restart.

    I'am not talking about netstat results. Postfix can be started and show up at netstat even if some parts of the postfix startup failed. And this is logged to the mail log then. So which lines had been added to the mail log as you restarted?
