Here is the issue I'm having, that I can't seem to get my head
wrapped around, as it only happens to one user.
When this user sends an email from their computer at work,
everything works fine, and if they take that computer to Panera, or
any other WiFi hot spot, everything also works fine.
However, when they take their computer home, they are unable to
send messages.
Your problem is probably that your users are submitting mail to the
server using port 25. Many ISPs block port 25 allowing only mail
submissions to their own mail servers on that port.
To get around this you need to set up your server to accept mail
submission on the mail submission port 587, what you should have done
in the first place. Then have all your users re-configure their mail
clients to use port 587 instead of port 25 for SMTP mail.
