I have a user subscribed to my list as: [log in to unmask] From what I can see on theweb interface the name and address in the list are completely normal. However, I just got this error (usually there are no errors for this list member): 1 09/24 09/24 [log in to unmask] Last error: SMTP; 553 <[log in to unmask]@DOMAIN.COM>... No such user The server seems to be jumbling around the name and domain in very weird combinations. Is it really possible to misconfigure a mail server badly enough to do something like this (I'm trying to imagine how ...). ----- Tom Rawson [log in to unmask]
