Hmmmmm, how did you know my alter ego! I'm your typical admin that is new to SPF , so I am now learning a bit more. I now understand more what SRS is about as well.
So really it somes down to , on failure: Either 1) the sender gets an email from [EMAIL PROTECTED] that the email sent to [EMAIL PROTECTED] did not work out, which confuses the hell out of the sender, cause he/shee sent it to [EMAIL PROTECTED] 2) the sender gets an email from [EMAIL PROTECTED] that the email sent to [EMAIL PROTECTED] did not work out, which confuses the hell out of the sender cause the person exists. Does this not mean that exchange will need to do this by default when setting a CR (assuming MS will provide this SRS functionality in a patch) -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Chris Scharff Sent: Wednesday, 25 August 2004 10:34 a.m. To: Exchange Discussions Subject: RE: SPF Warning 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.
