Scott, Thank you for your prompt reply. Yes, indeed, I'm hiding the true maildomain name.
All DNS checks are successful, there are no HOSTS file entries on the sending server. All mailhosts have proper MX'es pointing to proper A Records. There is no reply at all from the first MX. IMail just does not use the secondary MX. as it is proposed in RFC-2821: ------------- Begin Quote from RFC-2821 The destination host (perhaps taken from the preferred MX record) may be multihomed, in which case the domain name resolver will return a list of alternative IP addresses. It is the responsibility of the domain name resolver interface to have ordered this list by decreasing preference if necessary, and SMTP MUST try them in the order presented. ------------- End Quote from RFC-2821 Marius -----Original Message----- "maildomain.com" doesn't have any MX records, so it won't be able to receive mail. I'm guessing you are hiding the domain name (please use "example.com" when doing that, so people know what you mean, and you won't cause issues with an innocent domain).
