Would An Autoresponder For My Domain Email Trigger A Listing In Cbl Databases In Response To Spam Received?
Over the past several weeks, my mail server ended up in the CBL/XBL block lists, with some domains refusing to accept my email. I don’t have an open relay or an open proxy, and my anti-virus and patches are up-to-date. I wonder if this would be caused by my autoresponders to the postmaster@domain.com address, which, when replying to spam emails with false addresses, might be causing the server receiving my reply to think that my auto-response is spam.

If you’re sending mail to the postmasters of domains forged into spam headers, it’s entirely possible you’re hitting some address that feeds the CBL. Note that it’s IP-based, not domain-based, and you can look up your IP address to see its status.
My advice is not to use an autoresponder on spam; the FP rate’s too high unless you have a really, really good parser.
