It has been brought to my attention that a few clients have been trying to send me emails to my account, however they keep getting them bounced back and I never receive them.
This is one of the messages they get:
Sorry, we were unable to deliver your message to the following address:
Remote host said: 550 http://www.spamcop.net/bl.shtml?184.108.40.206" [RCPT_TO]
What does that mean and how do we fix it? I don't understand if it's a problem on the senders end or ours.
Thank you for any prompt assistance.
