Hi Rich, AOl is now blocking all direct smtp cnxns from dynamically assigned
IP's as an anti spam action.  

I assume you are attempting to connect directly from your system to AOL
without relaying your mail through ATT/Comcast's mail end user relays.

This won't work.  You will need to add some info to your mail config to 
handle it:

Add the following to mailertable in /etc/mail/mailertable
##################################################
aol.com		smtp:mail.attbi.com
########################################


You need to change  smtp:mail.attbi.com to whatever your
ISP has set up for accepting email from MS-WIN users.

And restart sendmail.
