Awhile back I noticed that the amount of spam (basically a dictionary attack) against one of my domains (notifymail.com). It was so bad that the load average on my server kept going up just to reject the mail for addresses that didn’t exist. I went ahead and used the email forwarding of my domain registrar to handle the incoming email. My server load went down and all was fine. Today I turned mail back on for that domain and instantly my server got flooded with email to that domain. So I had to move email back to the domain registrar; I lose some control over my mail, but it is my only choice. Too bad that the domain is basically dead; I’ve had it for years and really liked the domain as it was one of my very successful products.
