    Suddenly three days ago, one user at one domain cannot send mail into one email address at one domain on my server.

    User1@othercompany.com cannot send mail to UserB@oneofmydomains.com

    First, this message, then it eventually fails.

    This error was caused by an e-mail sent from somebody@micemetery.com

    How so? it only happens when certain people from the that other domain send mail to one person at the domain on m y server.

    Can greylisting work for only one address?
