 From what I gather, your web server's sendmail is intercepting the the 
email instead of routing it to the correct mail server because it has 
the same domain name as the recipient address? You need to manually 
create a rule in the sendmail to override that so it routes all email 
addressed to "@yourdomain.com" over to the correct external mail server. 
See the sendmail section of 
http://www.mail-abuse.com/an_rteoutgoing.html for an idea. It's been a 
long time since I hacked sendmail.
