Hmmm... How exactly are you sending the test e-mails? There are two
circumstances where the masquerading setup you've configured below
won't be applied:
i) Messages sent by root or any other user in class {E} -- however,
you've already put root into class {L} -- local users, so you
wouldn't use that account for testing masquerading anyhow.
ii) Unqualified names (ie. without an @... part) given as the 'From'
address. Try adding:
FEATURE(`always_add_domain')dnl
mail(1) just uses your login ID as the originating address, and
it expects the local MTA to fill in any missing information.
Other mailers generally have options to let you choose the
e-mail address you use to send from. However, sendmail will
generally qualify any names with the local domain when relaying
to another machine.
Aha! You're using LOCAL_RELAY --- try changing that to MAIL_HUB. You
may or may not need 'always_add_domain' with that -- you'll have to
experiment a bit.
