Server Fault is a question and answer site for system and network administrators. It's 100% free, no registration required.

I'd like to use multiple servers for sending mails like so:

server A: news@domain.com server B: all other addresses for domain.com.

The most important thing is the ability to send mails from server A.

I'm wondering if this is possible and if it is, how would I go about configuring this in terms of dns/spf records etc?

v=spf1 a mx a:mx1.domain1.com a:mx1.domain2.com a:mx1.domain3.com ~all

Assuming you have mx1.domain1.com pointing to server one etc.

OpenSPF.org has a nice SPF record generator.
