Spam because of this list

[Antiphon]

I use a free pop email service and am finding that this address is 
continually bombarded by swen virus spam because the debian servers do not 
munge addresses.

Is this going to be implemented anytime soon? My pop server only has a 6mb 
limit and since I leave messages on the server for pseudo-IMAP efficiency, 
I have to periodically go into the Web version and delete the spams, 
otherwise my account gets disabled. Lately, I've had to do it at  least 
once a day. I don't have the time to go and do this so often so 
occasionally my account gets disabled.

For the other lists that I participate in, I have received no spam because 
the addresses are properly munged.
