you dont need MX record for home operations, but make sure dyndns does not set
it up for you.
do
nslookup
set query=mx
youdomain
or set query=any
yourdomain
and make sure there is no MX records anywhere. also since you use DDNS, other
DNS servers might take their time to update records (they use cached old ip), so
thats another reason.

This webserver is connected to the Internet using an ADSL line with a dynamic IP. Due to the dynamic IP I'm running dyndns.org's MyDynDns service, so that I can have my own domainname on this server.

The sent messages aren't bounced back to the sender either, and (obviously) I can't find them anywhere on this server.

In the absence of an MX, mail to a machine (for example @yourcustomdns.com) will be handled by that machine (in the case of my example, the machine at yourcustomdns.com). This is the behaviour that most people running mail servers on their home machines want."
