Is anyone else starting to see bounces of the form
... while talking to air-xj05.mail.aol.com.:
>>> RCPT To:<[EMAIL PROTECTED]>
<<< 550 SomeMember IS NOT ACCEPTING MAIL FROM THIS SENDER
550 <[EMAIL PROTECTED]>... User unknown
I have started to see more and more of these, and I find myself wondering whether AOL members (and possibly on other services) are using the ever-expanding "spam blocking" facilities as a shortcut to leave lists, rather than figure out how to do it at the listserv level.
I am not sure it is a "spam blocking" facility. It clearly states it does know now the use and returns a 550 which means it is permanent. More than likely the user went away or deleted that profile and created another one. Deleting their membership is about all you can do.
Maybe if we worked with AOL and MUA makers to translate the RFC2369 Unsub header into an equally easy "button," members would use it?
Getting these idiots is one of the crosses you carry for running a list.
