Hi,

Is there a way to change POP Collector so it can handle when ISP changes headers with the X-Envelope-To field rather than RCPT-TO field?

This is for a global mailbox (multiple users, one mailbox).

Cheers.

Currently no there isn't, I'm afraid. Having said this it wouldn't be too difficult to add the facility to read other headers in deciding where to forward - this has been suggested also as a way to handle BCC on some servers. I will look into this when I get a chance (which may not be for a couple of weeks currently).
