Question....
I will be a little vague, as I am sure spammers watch this list, so bear
with me...
I have observed certain emails coming thru spamassassin, the one thing
peculiar is the existance
of an IP address that is not a valid address, i.e. it has certain
peculiarities that in text, completely
make it a bogus message, not a doubt about it. I was wondering if there
are any rules already
available that validate an IP address. I have written several custom
rules for my servers, however,
this may have to be done with a plugin, I do not want to re-invent the
wheel if someone already
has written one.
