If I'm connected to provider1, a nslookup for smtp searches for 
smtp.provider1.com, whereas in a connection to provider2 smtp is 
resolved as smtp.provider2.com. For BIND, I have to configure CNAME 
entries from smtp.provider*.com to the real name.

I think sendmail is the bigger crap :-)

My dialin-script could call "ndc reload".

Wouldn't it be better to define them as forwarders?
