Hi,

I have a client thats receiving emails from a mailing list. When the emails get delivered to their backup MX provider, the email headers get changed. The backup mx provider provide a pop3 mailbox to collect any queued email.
It seems that when exchange SBS 2003 pop3 connector collects the emails, it cant figure out which mailbox to place the emails in, so it just puts it in the admin mailbox.

Is there any way to get Exchange to use the X-Envelope-To field to route the emails from the pop3 collector?

I've found loads of people with the problem, but no solutions:-

SBS POP3 Collector is a piece of Junk. You should consider using a reliable program for this, as even Microsoft themselves state the POP3 Connector to be unreliable...
Try one of these, they will allow you to do what you want:
