Forward to other addresses

Hi,
Regarding the option 'forward to other addresses' under Edit Mail and FTP users -> Mail forwarding settings:

This only works if you specify account names rather than full email addresses. This is either
* a problem with my configuration
* a bug in that it should allow full email addresses
* a bug in that it should warn you if you enter a full address or disallow it

Usermin does work with full addresses which makes it doubly confusing to explain to domain administrators.

Any thoughts?
