Ignore auto responses from the vacation messages for given address

[vladt at broadsign.com]

As it stands when using the vacation e-mail system in sieve, messages will not 
be replied to when they come from a mailing list. I thing this is a postfix 
feature but I am not sure. Does someone know if is it possible to make 
general settings (not yet another user filter in sieve) which does the same 
thing with  given addresses (for example support at mydomain.com). I need a 
settings that allows this given addressed to not get auto responses from the 
vacation message system.

Cheers
