    When trying to use SMTPS server on port 465, I get this message on the server side (IP address hidden):

    NOQUEUE: reject_warning: RCPT from unknown[1.2.3.4]: 504 5.5.2 <localhost>: Helo command rejected: need fully-qualified hostname;

    How can I configure postman to change the hostname used in HELO? I see no way to configure this on its admin interface.

    Please help!

    Oh, and by the way: the machine that runs apache DOES HAVE an FQDN and it was setup correctly! If I issue a simple “hostname” command in the terminal, then it gives me the fqdn. But for some reason, postman sends “localhost” in the HELO, and I do not see a way to change this.
