There is no configuration needed on the LON-CAPA side. You need to
have a MTA such as sendmail installed and able to forward messages for
external recipients. I would expect CentOS would include sendmail by
default in a minimal install.
rpm -q sendmail

I would recommend taking LON-CAPA out of the equation and starting by
seeing what happens when you send e-mail to an external e-mail account
from the command line on schubert.tmcc.edu
mail -v ljensen at mail.tmcc.edu
This is the message.
Now I'm done
I assume you are using sendmail
ps aux |grep sendmail
Running host -t MX mail.tmcc.edu to retrieve the MX record for
mail.tmcc.edu suggests that googlemail provides mail service for this
You could check if access to the SMTP port (25) of the mail servers
which handle mail for mail.tmcc.edu is being blocked somewhere between
your server and the mail server e.g.,
telnet aspmx2.googlemail.com 25
If this is not a firewall issue you may need to use a text editor to
m4 /etc/mail/sendmail.mc > /etc/sendmail.cf
to regenerate the sendmail configuration file.
By default sendmail should be configured to only send and receive mail
within your local network.
This is set by the following line in /etc/mail/sendmail.mc
