Alias named admin?

[Mike Holcomb]

I have a little problem, I can't create an alias named "admin".  

For example, I have domain foo.bar, and a user named Alice. 
alice at foo.bar is fine, but she wants to be able to get mail from
info at foo.bar and admin at foo.bar sent to her alice at foo.bar account.

When I create the info at foo.bar alias, everything works fine.  When I
try to create an "admin" alias in the user manager, I get the
following:

Errors:
Email address admin at foo.bar collision 

Is there any way around this issue?

Thanks,
Mike
