my IP is on a blacklist and can Mail.com does not help.
I use hotmail, gmail and yahoo: no problems at all! only Mail.com blacklist errors...

"Please request a de-listing from your IP address from the pages that have your IP address in their blacklist.
You can request a delist. (dnsbl.spfbl.net)
Thank you for your understanding.
Best regards,
mail.com Support Team"
