<snip>

SUMMARY: 3 separate servers upgraded from RH7.0 to RH7.3 - all can send/receive mail locally and to/from the outside world EXCEPT for/from each other - which was not a problem under RH7.0. Do not believe there are errors in config files, particularly /etc/mail/local-host-names, and I have read the part of the sendmail FAQ about "mail loops back to me" and it DOES NOT APPLY in this case.

I've been through what sendmail documentation I can understand - can someone tell me what has changed somewhere prior to or at 8.11.6 which shipped with RH7.3 that might cause this?

I have another identically hacked RH7.0 server which I hope to rebuild/upgrade tonight - it will be interesting to see if all FOUR servers have the same problem.

I'm losing mail which is supposed to be forwarded between these servers.

Dick, I fought throught this myself recently when going from RedHat 7.1 to 8.0. I believe (not sure!) that the change occurred in RedHat 7.3. 1. sendmail is broken up into 2 separate processes for security reasons. One is outgoing, the other is incoming. 2. /etc/sendmail.cf is no longer used. There are several files in /etc/mail to replace /etc/sendmail.cf. 3. The new *.cf files are generated from several macro-preprocessed files. You get to edit sendmail.mc and submit.mc. The documentation in /usr/share/doc/sendmail/README.cf is good, but long. 4. The *.cf files are generated by the macro files when you start the service. (See /etc/mail/Makefile.) 5. The file /etc/mail/access can define where your server will accept relay mail from. I used the access file to allow all my domain machines to be able to use my alias list. However, I suspect that I should be handling my aliases differently -- I haven't gotten around to figuring it out yet, but this now works. I wish I could help more, but I'm pretty green with sendmail. Bill
