    Hello, I really need your help here...

    I've set up a postfix mail server for a single domain a couple months ago, and I'not able to receive mails from a few domains, always same ones.

    After a tcpdump I found out that, when receiving mail, the mail server is not identifying itself when issuing the HELO command, instead of replaying:
    " says HELO to w.x.y.z:port#"

    it just replies:

    Thanks in advance, Jose

    Please try to telnet mail server & paste the output.
