Feature request: allow null address in rulesets

[Jim Holland]

Hi Julian

Rules such as the following do not work:

        From:   <> and To: user at domain          yes

as I presume that the brackets are stripped off any addresses when
evaluating the rules.  Having the ability to set up rules such as the
above in spam.blacklist.rules would be useful when a particular individual
was being bombarded by bounces due to a Joe Job, for example.

Would you be prepared to provide for the use of the <> address in rulesets?
