External user (USERX) in another mail system sends out an email to;

- USERA in our GroupWise system.
- USERB in another external system.

Note: Two USERB's in our GroupWise system happens to exist as;


So, USERA gets the email, and
USERB in the external system ... AND ... USERB in our GroupWise system BOTH get the email.

USERB in our GroupWise system should NOT be getting it.

Any way to clear this up ? I hope it is clear to you ...
