I just got an email back (on my home account) saying "our software detected a problem with your email - or something like that" Problem is, I recognized the sender. It's someone I contacted - but a long time ago. I didn't send them anything recently. Plus, I periodically get "message-daemon, mail not deliverable" messages from accounts I don't recognize.
Where do I start? What do I look for?
Do I have to leave the Shire?
Uh oh, you better get a hold of...........
