My server was hacked and I've managed to get everything back online and working and hopefully the hole they got in from is plugged, I now have secure passwords in place. Hopefully that was how they got in.
My next problem is that over the course of a couple of days a lot of emails came from my ip. So much so that my ip has been blocked by most receivers. Google wont accept my mail and outlook never did, but now it doesn't even go to spam folders.
I'm trying to start a business. I have the sites back up and running. But I need to be able to send and receive emails. What should I do. Would changing my IP make a difference? Or maybe I should notify Google somehow? What are the next steps to getting my emails received?
Edit:
Ok it's been a few days and I've checked on mxtoolbox. The results say everything is fine. The server has no problems. I'm not listed on any blocklists. But I still can't send or receive emails. Only emails from my system to me get through. Server has 451 4.3.5 server configuration errors. Not sure what to do.
Edit 2:
I corrected an error with my Sender Policy Framework record. Outlook and Gmail still will not accept my emails. I've contacted them though hopefully it won't be to long before they ease the restrictions.
