Blacklisting by server hostname

[Stephe Campbell]

I must not understand the question and response from Mr. Field for the part
about the *.domain stuff below (second part of the question).

I regularly add to my spam.blacklist.rules file lines such as:

FromOrTo:    *xxxx.yyy    yes

to block things such as ghtr at m1.xxxx.yyy and vety at m4.xxxx.yyy.

It seems to work fine for me. What problems will this cause for me
eventually and what am I missing?
