The reason I think it's Dovecot generating the error is because when the 
IP address of the sending server is not in the mynetworks directive of 
postfix I get the following error:

Sender address rejected: not logged in> #SMTP#

When I do add the address of the sending server in mynetworks in 
postfix, the email gets delivered. However, when that person tries to 
reply to that email, they get the following error:

user unknown. Command
output: doveconf:

I realize that's a different error from my original message, I don't 
remember exactly what I did so I can duplicate the previous error, but 
the problem still persists. Dovecot is not able to lookup the recipient 
from AD because the recipient is in a different container. I simply need 
to find out how to get Dovecot to do LDAP lookups from the domain root. 
When I set the domain root in base = dovecot stops doing ldap lookups 
and it doesn't work at all.
