I've just set up sendmail to send emails from joe@javawag.com from within PHP (javawag.com is my domain and I have google apps mail set up on it). The problem is, when I read the mail I receive, it says "joe@javawag.dyndns.org"... this is what javawag.com resolves to (javawag.com -> javawag.dyndns.org -> [my dynamic ip address, changeable]). I'd like to have it show up as javawag.com however, so does anyone know how to do that?

BTW, I'm setting the from: header to joe@javawag.com, but it still shows as joe@javawag.dyndns.org (this also means it falls into my spam folder!)

Why would it get marked as spam for that? –  grawity Mar 9 '11 at 9:47
or perhaps it's because the subject and/or body were near enough blank... but it was marked as spam! –  Javawag Mar 10 '11 at 1:07

You want to use the MASQUERADE_AS feature in your sendmail.mc file:


Make sure javawag.com is listed as a local domain (although you presumably already do that).

You may also need FEATURE(`allmasquerade') and/or FEATURE(`masquerade_envelope'), depending on your setup; see the sendmail documentation for more information.
