I'm setting up an spf record for my domain.
v=spf1 mx:mail.domain.com -all
which works fine except that my mail server is behind a firewall and all traffic goes out through it. The firewall ip is for example. 188.8.131.52
I'm getting bounces from other servers that say that 184.108.40.206 is not authorized on my spf record.
How can i include it?
