Nobody should, but some do. Whether or not it's sensible, it's something that some people deal with. > The fact that SPF can't handle forwarded mail is a failure of SPF, not > a bug in forwarding. It doesn't matter if it's a failure of SPF or not. SPF is something one has to deal with if one wants to get as much of the mail delivered as possible. > Uh, no.

ITYM "harder to do it the old way successfully." Pull instead of push, or use SRS or other header rewriting and don't try to stretch a domain's SPF accountability beyond the IPs they publish, and it actually isn't that hard. Heck, I SMTP auth relay my role account mail into Gmail to bypass all of that and it works just fine. Email forwarding itself isn't bad, we agree. External old school dot-forwarding is outdated and too prone to failure. Tilt at that windmill all you want, but that doesn't really change anything.
