Hello,

I know this topic is not really postfix related but advice would
nevertheless be appreciated.

I'm adding a second mail server to my setup, my domains are
spf-protected by this simple entry:

v=spf1 mx -all

If I add second DNS A entry for my MX server will this still work or do
I have to list ips individually? Or should I create multiple MX entries?
The reason I don't want to do that in the first place is that there are
a lot of domains and I'd have to set the entries manually.

Thanks
Volker
