OK, so we know Comcast will admit that a user doesn't exist. Is this
a personalized list? Maybe Comcast does something different with a
multiple recipient RCPT TO that contains multiple invalid users?
Also, note that this message, presumably a quote from comcast.net up
to the open paren, includes an extended status code whereas the OP's
error did not. I wonder if his MTA was actually talking to
comcast.net? Maybe somebody gave him a "comcast.com" address by
mistake or something like that?
