Why my ip address is blacklisted?

Here are the possible scenarios:

  • you personally send spam from this ip
  • someone use your ip address to send spam, do you have you own ip addres or share ip with other users?
  • your mailbox was hacked
  • your mail server is insecure [relay problem]
  • you send emails without valid PTR record [Reverse DNS lookup]
