Hi. All of a sudden I keep getting bounce back emails fropmk customers that I regularly contact on email. The message is: SMTP protocol diagnostic: 550 SC-004 (SNT004-MC4F48) Unfortunately, messages from weren't sent. We recommend that you contact your Internet service provider. The problem is that too many unwanted messages have been sent from the following IP address above. I am not a spammer just a genuine business. Can some one help me to get unblocked. I am happy to enrol in the various programs etc. Thanks.
