[gentoo-server] Strange Mailserver Problem with dynamic DN

[Rene Zbinden]

I recently installed a Mailserver as written in:
http://www.gentoo.org/doc/en/virt-mail-howto.xml
I am using DNS Made Easy (like DynDNS) to point my Domain to my dynamic 
IP address. Now almost everthing works. I can send mails outside my 
domain but when I want to send an email to myself something strange 
happens:
When I send an Email from my ADSL provider (solnet.ch) then I can 
receive the email. Here the postfix log:

But when I send a message from another account (bluewin.ch) then I NEVER 
receive the mail and I get no error messages. It seems that those emails 
go to nirvana without notification.

When I do:
*Code:*
dig @nameserver -t MX my.domain


Then I see correct MX record. Any suggetions? Is it possible to trace an 
email?
