I normally use exmh, and when I try to send mail it now fails. I've tried using the comp program in nmh, and that fails as well, proving that exmh is not the problem. From the whatnow prompt, the error message is: What now? send david.ogilvie at yale.edu: loses; [USER] 550 <david.ogilvie>... Relaying denied post: 1 addressee undeliverable send: message not delivered to anyone The file /var/log/maillog shows the following (excuse the linebreaking): Apr 28 15:28:38 grendel sendmail[3512]: PAA03512: ruleset=check_rcpt, arg1=<david.ogilvie>, relay=IDENT:dbo@localhost [127.0.0.1], reject=550 <david.ogilvie>... Relaying denied Apr 28 15:28:38 grendel sendmail[3512]: PAA03512: from=<dbo.yale.edu> , size=0, class=0, pri=0, nrcpts=0, proto=ESMTP, relay=IDENT:dbo@localhost [127. 0.0.1] It's entirely possible that the problem is actually in the sendmail configuration. Something's clearly busted though. Btw, I created a new user and tried this from the new account, and the same stuff happened. So it's not some funky thing I did to exmh in the past.
I have not installed 6.0 yet, but from your description it definitely looks like a misconfigured sendmail. You should try to configure your sendmail to accept relaying at least from localhost. In 5.2 the relevant configuration files were in /etc/mail directory
Forced a reinstall of sendmail, and everything works now. Odd, because I swear I tryed that before. Guess I should have done a rpm -V. Sorry for the bug report, and thanks for a great distribution.
This sounds like it has been resolved. Please reopen if not.
