A few weeks ago transactional emails from my ecommerce website (new account signup, lost password request etc) started bouncing back with the message:
host [url removed, login to view]
SMTP error from remote mail server after end of data:
550 This message has been reported as spam by other users.
This issue happens with emails send to : Yahoo, hotmail, Gmail, AOL, etc.
My webhost told me that this is not a server issue, and my IP has not been blacklisted (yet).
I do not use my email for newsletters, and apparently normal emails (when I reply to someone) are not bouncing. It appears to be related to my automatic transactional emails only.
I have my email setup well, with dmarc and whatever, and I get a 9/10 or 10/10 score when I test my email on [url removed, login to view]
I need a security / email expert to :
-give me some insight why this is happening
-analyze the bounced emails to see if there is an IP address pattern (maybe someone is deliberately trying to get me blacklisted).
-and, most importantly, do whatever needs to be done to stop these emails from bouncing. Including contacting the email providers and getting me listed on a white list.
When you place your bid please make sure your proposal outlines what you will do, and what you cannot do to get this bouncing issue resolved.
