Thanks for your help and advice.
I installed Postfix and was surprised the amount of files processed in the terminal. I'm at a loss to understand why the XAMPP install did not do this correctly. I followed your instructions and also commented out the sendmail lines. I used MX to do a DNS lookup for my email and the mx01 is the #1 preference for windstream.net domain (see next paragraph).
I reloaded postfix and resent my form data. It looks like the mail is finally going to my mail server but checking the mail.info log under /var/log I see the following:
Jan 10 13:02:13 ted-desktop postfix/error[4667]: D6FAC182AEB: to=<tkokkinos@windstream.net>, relay=none, delay=366, delays=366/0.01/0/0.09, dsn=4.7.1, status=deferred (host mx01.windstream.net[162.39.147.49] refused to talk to me: 554 5.7.1 - ERROR: Mail Refused - <173.188.48.94> - See
http://www.spamhaus.org/query/bl?ip=173.188.48.94) ------> at least now it is finding my email address correctly.

Checking out this spamhaus.org link I see:
Ref: PBL424785
173.188.32.0/19 is listed on the Policy Block List (PBL)
Outbound Email Policy of Windstream Communications for this IP range:
It is the policy of Windstream Communications that unauthenticated email sent from this IP address should be sent out only via the designated outbound mail server allocated to Windstream Communications customers. To find the hostname of the correct mail server to use, customers should consult the original signup documentation or contact Windstream Communications Technical Support.

Looking at this, is seems obvious that now my problem is some type of blocking by Windstream. I guess that I can test this using a Gmail account or some other such nonsense.
Do I need to do some type of authenication or is Windstream just being a pain and my best bet is to use another email server like Gmail?
