mail server host name is in greeting

    Question

  • I hope someone here has an answer to this.

    I went to dnsreport.com and tested our exchange server.

    Received a warning that the "Mail server host name in greeting".

    I checked a header of an outgoing email, and it is showing our internal IP's and server names of the domain controller (Win2003 Server), Our Exchange Server (Win2003) and our email scanning machine which is an WinXP SP2 machine.

    I checked the smtp virtual directory on the exchange server and the Maxiumum hop count = 30, Masquerade domain is our domain name, Fully -qualified domain name: is mail.xxxxxxx.com, Smart host: [xx.x.xxx.xxx]...the ip of the exchange server.

    And I restarted the smtp service.

    I also changed the banner.  So what now am I missing.  I have been around and around on this for days.  Please help before insanity sets in.  Thank you in advance.

  • Hi,

    What response do you get from DNSReport after you've changed the SMTP banner?
    Have you also changed banner for POP3 and IMAP4?
    Is your Exchange the primary incoming mailserver or the WinXP machine?
    Are you using your WinXP scanning machine for both incoming and outgoing e-mail?

    Some links that might help:

  • You can hide the server name in greeting/banner, but you cant remove it from the SMTP mail header.
    You could write a transport sink that cut stuff from the SMTP header, but you actually violate the RFC if you do.
