Hello Diana,

Thank you for your question regarding an email returned due to IP blacklisted with SpamCom. I first recommend using our Bouncback Parser tool. It can help narrow down the cause of returned emails, or even notify our system admins of issues.

If your problems persist, I recommend submitting a full example of the returned email to live support so they can look at y our specific server and correct the blacklisted IP.

Thank you,
