I believe the terminology is different between sendmail and postfix and
maybe that is why I am confused.

With Sendmail I was able to use the masquerade_as flag and specify a A or
or MX record that Sendmail would disguise all outgoing mail as.

So, say my host is linux.domain.org and I have a mailhost at
mail.domain.org, I was able to set masquerade_as('mail.domain.org') on
linux.domain.org and all mail going out would appear to come from
mail.domain.org rather than linux.domain.org.

Is this possible with postfix? I know that I can make linux.domain.org
look like domain.org using masquerade_domains but can I make it look like
a different host?

On a related note, anyone out there got any tricks for automatically
dealing with large *map tables in postfix? Say I've got another mail
server running LDAP and I want postfix to handle delivery and rejection
for all mail in the domain, can I do something clever like query the ldap
server to generate the map file for postfix? Seems like it should work but
i am curious if anyone else is doing this sort of thing...

Oh yea, reply offlist please. Thanks!
