Thanks for your input on this. My main concern is mail filters at the
end users side thinking that our mail servers are spoofing our
customer's domain. I'll check into MAAWG as well

#Some customers insist on
#making the FROM address use their domain name, but the emails leave our
#mail servers on our domain. =20
Then your IPs or outbound mail servers should be listed on the
customer's
SPF record... assuming they also send their own mail, they obviously
also
want to list their own mail servers.
#SPF seems to be the way we could possibly avoid more spam filters,=20
SPF only provides a way of avoiding spoofing, it does not necessarily
enhance your IP reputation or your domain reputation
#and delivery rate is very important to our company.
Are you involved with MAAWG? (see www.maawg.org)
