To: and "not From:" Ruleset Option?

[Ian]

Hi,

I don't think this is possible but would like to here your opions:

I use several different email addresses for various mailing lists.  Sooner or later these 
addresses get spammed.  I would like a Spam Blacklist rule like:

To:	mailinglist_local_address at mydomain.tld	AND NOT From: 
maillinglist_sending_addr at mailing_list_domain.tld	yes

(all one line)

Is this possible.  I have read the MAQ and examples and can't see this anywhere so I 
assume it isn't.  If not, could it be added in a future release?

I am not bothered about losing emails from people posting directly to me, the should be 
posting to the list anyway!

Regards

Ian
