Hi-
I've been looking all over and can't find the answer to this one. I have a
CNAME alias (sabami.seaslug.org) with a local user's group that I want to use
as my mail server's hostname, so I've got this in my postfix config:
mydestination = localhost, localhost.$mydomain, $mydomain, sab.rresearch.com, sabmail.rresearch.com, mail.dsab.rresearch.com, $myhostname
mydomain = sabami.seaslug.org
myhostname = sabami.seaslug.org
myorigin = sabami.seaslug.org
to make sure I get all my aliases in the mydestination (is that necessary?). The way
things are configured is like this:
sabami.seaslug.org CNAME mail.dsab.rresearch.com
sab.rresearch.com CNAME mail.dsab.rresearch.com
mail.dsab.rresearch.com A 12.235.153.213
where that mail.dsab host is a dynamically updated DNS entry at a site where I have
direct control over the DNS server. What I want is for @sabami.seaslug.org to be the
FQDN that gets used on all email leaving my mail server. But, what seems to be
happening is that it gets rewritten (in the envelope sender, To/Reply-to header
addresses, at least) to @mail.dsab.rresearch.com. I assume there's some logic in
there somewhere that is converting CNAME references into the hostname on an A
record?? Is there any way to get what I want here?
Thanx!
