Welcome to the wonderful world of cyber detectives. Here's how I did it
once upon a time on grandteton:

- - Write a script which extracts all the domain names from the subscriber list.
  (sed s/^.*@//)

for $domain in $(cat domains); do
	host $domain >> mx
done

Now the file mx contains all the mail exchangers for everyone on the list. 
That's where you need to look for olsworld.com.
