Using dots in forward/alias names

[Antonio Nati]

Sorry to ask an obvious question, but I scanned all the mailing list 
without results.

I need to forward and address like [EMAIL PROTECTED] elsewhere.

I set up .qmail-mickey.mouse (with "&[EMAIL PROTECTED]" inside), but it 
doesn't work, while the user [EMAIL PROTECTED] works nice.

How to handle the dot inside the name?

Thanks,

Tonino
