OK, I finished one of my servers setup for sending, everything was quite right, tested on the seed list on gmail and all seems inboxing.
So I send my first campaign with only 1800 subscribers (only gmail and yahoo cleaned) list with 1 email per minute cron settings, and on the next day, the domain gets SPAMhaus DBL which is quite devastating for me, how the hell did I get in there??
Tried to delist using the DBL domain removal form it and they reject in automatically, when I try to send support ticket it gaves me "An error occurred. Please try again."
How to fix this?
