[3830] Duplicate Messages Being Received

[Jerry]

Hello:
I've been getting dual messages....that is, an exact copy of each 3830 
email sent to me.  I suspect that maybe I'm getting emails to my old 
email address and my newer one.

Old:   grf at uneedspeed.net
New:  grf at npgcable.com

How can I correct this?  This morning I had over 1500 emails most of 
which were from the 3830 mail group.  Many thanks for any assistance you 
may be able to provide.
