All my outgoing emails suddenly bounce as spam!
This is really strange. I've never had problems with my email server before (and I'm sure this isn't my email server's fault either).
Basically, most messages that i send out from my domain (@ablogic.net, or 207-234-130-118.ptr.primarydns.com) most of them bounce back (from servers that have spam filters), saying that this message is spam (some servers say that my IP is spam). The only thing I can guess is that somehow I got added to a blacklist or something, which’s used by most spam blockers out there. I don’t know much about anti-spamming technology, but that’s the only thing I can guess.
I’ve NEVER sent spam to anyone, my mail server is NOT an open relay, doesn’t have any open proxies (I consider myself a decent linux admin and know all my open ports), so the only thing I can think of is that someone added me to those blacklists by hand…
Now come to think about it, last week I reported a spam to some company named covad.net (or something like that) – their user was sending me spam from their servers, without even spoofing the username. Maybe they told the spammer that I reported them, and the spammer added me to the blacklist as a retaliation?
Can someone suggest anything? By the way, here’s an example of a bounce with file “undelivered message headers.txt”:
