There is an issue with -all. SPF does not work with .forwards or other relaying of that nature. If you can be certain that every recipient's final MX is the one your server sends to, then -all is OK, but you can't. The scenario is your list member is [email protected]. [email protected] is set to forward all mail to [email protected]. Yahoo receives the list post with envelope from [email protected] (or [email protected] if VERPed) for [email protected] from the server at example.com. The SPF for your.list.server doesn't allow example.com as a relay, so SPF fails at yahoo.com. -- Mark Sapiro <[email protected]> The highway is for gamblers, San Francisco Bay Area, California better use your sense - B.
