Attention Greg, so-called tutorials do not tell you what you need to 
know about Postfix. Consult the original Postfix documentation.

Configure Postfix to us relay_transport for the hosted mail domains 
feeding Cyrus-IMAPd on LMTP. And make sure you define proper 
relay_recipient_maps (or virtual_alias_maps).

relay_domains = example.org
relay_transport = lmtp:inet:[]:24
