I asked something recently as I have a couple of addresses that get nothing
but spam. I have to keep them as one is tied to my hosted domain and the
other to my web pages with my ISP.
A trawl of the list archive will pop up the answers, but basically you just
have to create a rule that's something like:
header LOCAL_BAD_ADDRESS ToCc =~ /onlyspam\@isp\.net/i
describe LOCAL_BAD_ADDRESS Envelope address is a known spam trap
score LOCAL_BAD_ADDRESS 10.0
I have the interesting problem that in my case I have a number of other
addresses that don't get spam but are identical except for a prefix
(fred.onlyspam, tom.onlyspam etc). I just created another rule that said
that .onlyspam rated a marking of -10, cancelling out the above. Probably
an easier way to do it, but it works for me :-)
Please DO NOT send me ANY email directly unless it's a privacy issue.
Reply-to mangled to assist those who don't read the above.
