Today’s Wednesday question comes from M. B. My company sometimes sends mail to our list on behalf of 3rd parties. A recent 3rd party told us that CAN SPAM requires the email contain their opt-out link as well as ours.

Poisoning Spamtraps

I wonder if spammers might submit harvested addresses to big-name companies known to not use confirmed opt-in just to poison what they believe might be spamtraps? It’s certainly possible that people submit addresses to forms and big-name companies. But I don’t really think that poisons the […]

  • AOL problems

    Lots of people are reporting ongoing (RTR:GE) messages from AOL today.  This indicates the AOL mail servers are having problems and can't accept mail.
