Troy, I'm sure there are people with far more experience in the details of email processing, but let me offer at least one thought.
I could be wrong, but I suspect CF would have no involvement in any failto processing after the email is sent, and my understanding is that the failto is a standard email header which mail servers handle themselves. So this is just enabling CFers to more easily specify that header. To be clear (to any who may wonder), this would NOT be at all related to the undelivr folder in CF. That's is indeed for when CF cannot even get the email out to the specified mail server (in the CF Admin or on the CFMAIL Server attribute). My understanding is that the Failto is for when it DOES get out and past that first server, and into the wider world of the mail system, where there is some subsequent problem (and therefore, the message could no longer be handled by CF or that undelivr mechanism, because there's no connection in the email to the sending server). The failto is so that someone other than the sender can get any response if there's a problem. Make sense? Anyone have more details for him? /charlie From: [email protected] [mailto:[email protected]] On Behalf Of Troy Jones Sent: Wednesday, September 29, 2010 9:41 AM To: [email protected] Subject: [ACFUG Discuss] failto attribute of cfmail I am wondering how the failto attribute of <cfmail> works. My understanding is that this is an address intended to receive NDR's that may be generated by a recipient's mail server should something be wrong with the mail attempt. If this is true, does this also mean that the designee would only receive a failure notice if the recipient's mail server generated one? Is it based on ColdFusion detecting some error code during transmission? Or, is there some other behavior that should be expected? Does anyone know of a definitive way to test this behavior?
