Since Monday, all the mails I've sent on my dedicated server were rejected.
I realized my server is on Spamhaus XBL because it was listed at ABUSEAT CBL. Never heard of it. So, I looked on my logs and figured the server was compromised and indeed sent spam from my e-mailaddress (only address that can relay).
I reinstalled the server. I figured some Indian guy is posting my e-mailaddress as contact info for his restaurant. I decided to buy a new domain name.
So far, so good. I got delisted on the CBL. I'm listed on the CBL AGAIN! And I couldn't find anything that has to do with spam. As long as I'm on the list, I can't send emails anymore.
What to do to stop these guys?!
