    I installed a few days ago a SMTP antispam server using postfix. My mail server is an exchange server and Im not using active directory.
    My problem is the following I configured (at least I tried to) postfix to receive mails without checking if mailboxes really exist in Exchange.
    These worked fine inside my network where I can telnet and send mails through my postfix and receive them correctly in the exchange. But when I try to do this from internet, I get an error saying that the mailbox doesn´t exist (550). I also tried to TELNET my box to the port 25 and I dont receive any answer (it connects but dont show any text).
    Can somebody help me please??

    Thanks in advance

    If you use Postfix' transports, then you don't have to create user accounts on the Postfix server. Something like this should work:

    echo "smtp  *:[<IP address of Exchange server>]" >> /etc/postfix/transport
    postmap /etc/postfix/transport
    /etc/init.d/postfix restart

    Actually. I did that, and thats why if I connect from inside my network using telnet, mails are sent successfully to the exchange box.
    The problems is when the connection comes from Internet.
    Any idea??

    What exactly is in your mail log when this happens?
