Does that now mean the RH 7.3 Sendmail host is protected by the firewall settings, so that from outside your net connections on port 25 will go direct to the Fedora host running Sendmail? Or does the RH 7.3 Sendmail can directly talk to other MTAs outside your net? I suspect former, but am not sure. > The 7.3 box just Whenever the 7.3 box sends mail out as root, its return address > is root@xxxxxxxxxxxxxxxxxxxxxx The 7.3 is not in the same domain as the Fedora > machine.

Do not test mailing using user root! First, it is a bad habit to use root for something else than administration. Do not use it for testing purposes or things for which you easily and better can use a normal user account. Second, root is an exposed user, see your sendmail.mc for that entry and the Sendmail documentation for comments: http://people.freenet.de/slgig/cfreadme_en/masquerading_relaying.html. So as root's mail is not masqueraded coming from the RH 7.3 host. I suspect that all other user address are masqueraded with the other domain. What I do not understand because lack of information is: why do the mail from Sendmail on RH 7.3 does get to the Sendmail on FC1? I suspect because either it is addressed to a user address on the FC1 machine or because on RH 7.3 you defined the FC1 Sendmail to be the SMART_HOST (either in sendmail.mc or in mailertable). So the question is then to where the email is addressed, whether for a recpient on the FC1 host or to outside. > In the sendmail.mc file here are the changes I have made: The sendmail.mc on FC1? not of the RH 7.3 host? > define(`confSMTP_LOGIN_MSG',`$j Sendmail; $b')dnl > define(`confSMTP_LOGIN_MSG',`$j Sendmail; $b')dnl > TRUST_AUTH_MECH(`EXTERNAL DIGEST-MD5 CRAM-MD5 LOGIN PLAIN')dnl > define(`confAUTH_MECHANISMS', `EXTERNAL GSSAPI DIGEST-MD5 CRAM-MD5 LOGIN PLAIN')dnl > define(`confCACERT_PATH',`/usr/share/ssl/certs') > define(`confCACERT',`/usr/share/ssl/certs/ca-bundle.crt') > define(`confSERVER_CERT',`/usr/share/ssl/certs/sendmail.pem') > define(`confSERVER_KEY',`/usr/share/ssl/certs/sendmail.pem') > DAEMON_OPTIONS(`Port=smtp, Name=MTA')dnl Suspecting the sendmail.mc being for the Fedora Sendmail host, you did not set up any other things like genericstable? I suspect you leaved the LOCAL_DOMAIN(`localhost.localdomain')dnl untouched in sendmail.mc. It would explain some guesses. > Hopefully I explained this a bit better. > > THanks! > > Dave Your original reason for mailing, was that a problem or just wondering? If you have a Sendmail setup difficulty I fear you have to be more precise again about what you want and what's not working as expected.
