[IMail Forum] Email being rejected

[Deb Chard]

Occasionally email that is sent to some addresses is rejected, usually with something like client host rejected:  cannot find your hostname.  I believe that what is happening is that some mail servers are trying to resolve the internal name of the mail server (email.headquarters.ilx.com) to the public external address of 216.167.71.99 when the external name is email.ilx.com.  This happens very seldom, and usually with email servers in foreign countries.  Is there something I should change/add in my Imail setup to account for this?    Thanks   Deb Chard ILX Lightwave
