I was wondering, suppose I have a user like this:

f...@bar.com is the account name
foo.lastn...@bar.com is the incoming alias and the outgoing canonical

Could I force incoming mail to accept the alias form, but not accept the 
account form? I.e. f...@bar.com as address is blocked, but foo.lastn...@bar.com 
is accepted and delivered to f...@bar.com

The spammers that send to my systems use the account form (and not the 
alias/canonical) a lot, that's why I'm asking

I can of course create a new account form (a...@bar.com) and use 
aliases/canonicals on that, but that might not take hold in the long term and I 
would have to let users change their auth settings (which now is user 'foo' and 
'password')

Yours,
