Hi,

Sinds a few days I get the following errors:
(E-Mail Removed)>... Deferred: Name server: mx3.hotmail.com.: host

[compton ~]$ host ga.nl
ga.nl has address 62.212.134.99
ga.nl mail is handled (pri=10) by mail.ga.nl
[compton ~]$ host mail.ga.nl

You want to have a talk with "xsdsl.net" and have them fix the PTR
record. There are quite a number of mail servers now configured to
reject mail from hosts when forward and reverse names don't match.
mail.ga.nl != 62.212.134.099.xsdsl.net

>Anyone ?? please?

You do have to allow for propagation delays - mail might go direct,
but news bounces from server to server. I'm about 1000 KM East of
Los Angeles, California USA, and the "Path:" header shows 11 hops
between us ;-)
