Andréas, that's great news. Re: > So, I must ask, what do you mean by the dot "fully qualify the domain"?
It's like the difference between "var/mailroot" and "/var/mailroot" Because dns is reversed in it's structure the "root" is on the right. Eg: Folders = /1/2/3/4/5 DNS = 5.4.3.2.1. What actually happens when you DIG without a root dot, is that it tries the concatenating the local domain of your pc/server as a suffix to your request. When that fails it tries one domain higher, etc until the local domain is just a dot, then it will find the domain as it should. So you dns queries should be marginally faster with a root dot. EG. Local domain is mydomain.com. Lookup FQ host, host.onedomain.com Resolves as host.onedomain.com.mydomain.com. This fails and tries host.onedomain.com.com. This fails and tries host.onedomain.com. Tada, resolved. Interesting to note I also have root dots on my CustMapsList.

Mine also worked without a problem until I put my xmail on another server. Funny thing - with your CustMapsList and after initial tesing - it works. So, somehow it's that tiny dot that makes all the difference. So, I must ask, what do you mean by the dot "fully qualify the domain"? Does this DNS-server work differently than the one I used to use? :P Maybe I should take the course "DNS 101" to figure this out. :o) Thanks for the help Jorn and Rob!
