So in any case, due to customer privacy concerns we feel we can't do that.
If you don't want to handle email for the long-obsolete customer accounts, but just don't want to send that mail to anybody else, it's pretty easy to run a teergrube or other tarpit system to trap any mail addressed to the A-record. These systems basically accept mail v.e.rrrr.yyyyy....s....l.....o...w...l..yyyyy so that spammers can waste their time talking to your tarpit instead of to somebody who cares, and so you can trap their IP addresses and potentially block them or use them to support your other spam-blockers if you want. You don't need a high-performance machine because all the users are spammers and you're *trying* to give them bad service. (Some variants, like LaBrea, are used for connection attempts to non-existent machines - they'll send a syn-ack so the attacker thinks he has a successful 3-way handshake, which slows down scanning attacks.) If you do want to accept mail for the long-obsolete customer accounts, so you can give them a proper human-readable rejection message, you may need to customize. It looks like Exim supports that, though I haven't tried it. -- ---- Thanks; Bill Note that this isn't my regular email account - It's still experimental so far. And Google probably logs and indexes everything you send it.
