Sendmail 8.11.6 (was building RH7.3 after hack)
I spent four hours on Google last night about this problem. Saw reports of the same messages, but not the same situation. 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

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

that's sendmail 8.12. 8.11 is still the single monolithic sendmail.
2. /etc/sendmail.cf is no longer used. There are several files in /etc/mail to replace /etc/sendmail.cf.
Actually it's still just sendmail.cf for the daemon, but it is under /etc/mail now. There's also a submit.cf for the "client" portion. What are the errors that are being seen? That wasn't specifically mentioned in the original post. There was something about the "MX loops back to me" thing, but I don't know if that's the error you're seeing or not. -- Randomly Generated Tagline: "A way out of financial mess is discovered as if by magic!" - stupid fortune cookie
