Hi list,
I operate several servers, one of which is at home, behind NAT. The
local network is configured to use the domainname "nieser.local.", which
obviously only exists on the local (forwarding) nameserver.
To be able to send e-mail from this machine (which would normally be
rejected by any MTA because of the non-existent 'from' domainname ) I
have configured sendmail to masquerade e-mail sent from the
"royen.nieser.local" machine as "royen.nieser.net" which resolves to the
external IP adress of the DSL gateway device (which has smtp forwarded
to the royen.nieser.local machine).
The above setup *mostly* (see below) works, e-mail that I send from the
server has it's "royen.nieser.local" hostname properly substituted with
"royen.nieser.net").
Now, to make monitoring all the servers I operate easier, I wanted to
forward all mail sent to root (including the periodic output), by
putting "root: [EMAIL PROTECTED]" in the /etc/mail/aliases file, as the
comments in this file suggested:
# Pretty much everything else in this file points to "root", so
# you would do well in either reading root's mailbox or forwarding
# root's email from here.
But here's the weird thing, the periodic mail doesn't get masqueraded
and therefore gets rejected by the remote MTA. The "rejected" message
which gets sent back to the root account, however, *does* get
masqueraded properly and subsequently forwarded to the e-mail I
specified in the /etc/mail/aliases file!
Mail originating from the root account is usually not masqueraded.
In sendmailese, root is "Class E", so your sendmail.cf probably
shows "CE root". You can probably override this by putting an
appropriate entry in your .mc file and then making a new config file
from it, but offhand I don't know what mc syntax you'd use.
Your bounces get masqueraded because the outside envelope is not
"From root" anymore, it is From your mailer daemon.
