I am an iMac desktop user with Safari as my browser. My Verizon email server gives me a pop-up saying "Cannot send message using the server Outgoing"..... and yet I can send out newer messages okay. I have about 6 emails now in my Drafts folder that refuse to be sent. They wind up in my Outbox....and just hang there. Receiving incoming okay...and can send new messages.... but why won't these half-dozen emails 'go out' ??
