Hmm. How are you going to establish a TCP connection without a handshake? 
The interface doesn't make any difference. Besides, it has nothing to do 
with Dovecot. Dovecot is the intended recipient, not the sender.

The LDAP server listens on localhost, and it currently has a connection 
established with dovecot-auth. Aside from Dovecot, NAT, DNS, Privoxy, 
and Squid all use localhost, so if the loopback wasn't working, I'd know 
about it pretty quickly. /etc/resolv.conf looks normal; it's got the 
search domains and the name server addresses.
