by default, mail goes to the MX of the domain. you can override that
with local transport maps, but these maps only apply to you infrastructure.
if you want mail to go to joe.example.com, you need to configure an MX
record in DNS:
example.com. MX 10 joe.example.com.
(Warning: the leading dots aren't just for decoration).
