Email Issues

If you and I exchange email on a regular basis...I HAVE NOT BEEN IGNORING YOU! I am having major outgoing email issues that may be working out now (I hope). But, if you email me and don't hear back from me...I am not ignoring you. I am also unaware until about three days after the fact when I get one of those "MAILER-DAEMON@yahoo.com, Delivery Failure" messages. So I have been blissfully unaware of my rudeness until that third day rolls around.
