I think MX record is documented fairly clearly on e.g. wikipedia. The rest of it spelled out in Defaults.py in my installation: - "delivery module for *outgoing* mail" (emphasis mine: "outgoing" means MX doesn't apply), and - "make sure the host exists and is resolvable". Presumably mailman is not doing anything fancier than import socket socket.gethostbyname() and your non-fqdn SMTPHost will not resolve if you try the above in python shell. -- Dimitri Maziuk Programmer/sysadmin BioMagResBank, UW-Madison -- http://www.bmrb.wisc.edu
