my mailserver handles 4 domains. i explicitly set the permitted sender ips on the spf entry for my main domain like v=spf1 ip4:(ip v4 addr) ip6:(ip v6 addr) and for the three other domains i redirect to my main domains spf record. v=spf1 redirect=domain.com i recommend you to read the rfc for all the possibilities to set up your spf record. - Christian
