email

Hi there,

I want to setup a second smtp server to receive emails when the primary server is down. The primary server is a configured by OS X Server, the secondary is a Postfix setup on Debian. The secondary is able to accept emails, but how to I push to the primary server?

I need a little hint where I have to look at the configuration (I do the most stuff with webmin (o: )

Thank you...

Rainer
