That's correct. That is the RFC compliant behavior by Exchange for both the scenario I described and instances where an external recipient is specified on a mailbox as an alternate recipient.... oh and where a member of a DL is an external contact.
How "SPF not happy" AOL will be at that depends on the settings used by the admin who created the SPF record for their domain. I have little confidence that folks who are unable to understand what a PTR record is or that an Mx record must be an A record are going to choose the correct settings for their SPF records. <Barbie>DNS is hard.</Barbie> > -----Original Message----- > From: [EMAIL PROTECTED] [mailto:bounce- > [EMAIL PROTECTED] On Behalf Of Dean Cunningham > Posted At: Tuesday, August 24, 2004 5:17 PM > Posted To: swynk > Conversation: SPF Warning > Subject: RE: SPF Warning > > You lost me on that one Chris.
