I have an IMAP/SMTP (comcast.net) account and three exchange accounts. The IMAP/SMTP account is default. I have no senders in the safe list. I have senders and sender domains in my blocked sender list. Here is an example I just got a few seconds ago: <email@example.com> and in my Blocked Senders list I have @eml.nordstrom.com. I ALSO have firstname.lastname@example.org in my blocked senders list. Yet this e-mail continues to show up in my inbox.
