I suppose your best bet is to use real human name derived usernames, rather than nicknames, placenames, or technical-sounding names. The other obvious solution is run a separate box for your mail service, that's not going to have other services running on it, and carry on using what already works fine for you. -- Don't send private replies to my address, the mailbox is ignored. I read messages from the public lists.
