Routing Outgoing Mail

Hi there

It becomes kinda hard to operate a mailserver hooked
to the net via ADSL with dynamic IPs. Setting up the
machine with Postfix and DynDNS is a piece of cake,
but a growing number of webmail services (like Yahoo
and GMX) are greylisting the dynamic IP ranges of
internet providers. When they receive a mail from an
IP out of a provider's ADSL pool, they go "hmmm, this
must be a virus infected PC" and put the mail in the
recipient's junk box directly. Other webmail services
perform a reverse lookup and – as the IP resolves to a
different domain name - they junk the mail as well.

Is it therefore possible to tell Postfix to deliver
mail to certain domains (Yahoo, GMX etc) via the
internet providers mailserver while delivering all
other mail to the recipients mailserver directly?

Many thanks for your help!! Peter
