Disclaimer: I don't run postfix and never looked at the documentation.

Your mailer is probably using the MX record for mail.mindspring.com
instead of the address record.

For test purposes try to replace relayhost = mail.mindspring.com
with  relayhost = IP address of mail.mindspring.com.

This can probably fixed using a special syntax like: 
	 relayhost = [mail.mindspring.com]
( Wild guessing - see disclaimer !!!)
to force postfix to use the address and not the mx record of 
mail.mindspring.com.

There has been a thread with the same problem using sendmail? recently. (last 
3 month?)
