First, check your spam filter.  Some spam filters
store rejected emails for a week or more.  Set
your spam filter to accept my emails (see below).

Some email providers do not like emails from asu.edu.
In particular, aol.com and worldnet.att.net are often 
finicky about accepting email from asu.edu addresses.

Here are some suggestions for possible fixes:

(1) Make sure that your spam filter is set to accept
    emails from both

                gary.adams@asu.edu

                       and

             gbadams@aries.eas.asu.edu

(2) Complain to your internet service provider that
    important emails are not getting through.

A sure fix is to use your ASU gmail account.  GBA
