hi there.

i have a webserver under www.example.net which has a prope
a-name-entry.

i have a mailserver example.net which only has an mx-entry.

now there are people complaning that they cannot reach my mailserve
because the host example.net doesn´t deliver an ip-address whe
using nslookup. so their mailserver is not able to send mail to m
domain although an mx-entry exists.

they say, that mailtransmission goes in two steps:

1. mailserver checks for valid domain by looking for ip-address i
a-name-entry.

2. mailserver sends out mail using mx-entry

if step 1 leads to an error step 2 isn´t even tried.

can anyone of you verify that?

next thing is that they told me, the simplest solution would be addin
the hostheader example.net to my webserver. this would lead t
example.net being resolved by dns.

can anyone verify that

Your post at a couple spots seems to be garbled. Not sure why.

Also, if you can post the actual domain name, it will be very helpful. We
can run a couple tests on it and let you know what we find, otherwise we'll
be guessing.

It could be something as simple as not having a "mail" record under
example.com, which the MX should be pointing to. Who knows?

Thanks!
