Well, I applied the latest patch to my Sendmail config and have managed to stuff it up well and truly. I am running RH9 and Sendmail 8.12.11.20060308/8.12.8. SMTP authentication stopped working first and in trying to fix it I managed to tie myself in knots. I ended up with errors like this: Mar 27 15:29:01 mail sendmail[16518]: NOQUEUE: SYSERR(root): /etc/mail/sendmail.cf: line 84: fileclass: cannot open 'ATURE(`access_db',`hash': No such file or directory In the end, I deleted sendmail.cf and sendmail.mc and forced rpm to install the new version again. This solved the above problem and Sendmail is now working to a degree, ie, those hosts in /etc/mail/access are able to relay mail, which is fine. Mail is delivered to pop3 accounts. However, I'm getting these errors: Mar 27 18:27:41 mail sendmail[641]: STARTTLS=server, error: SSL_CTX_check_private_key failed(/etc/mail/certs/key.pem): 0 I'm also getting this: Mar 27 18:07:07 mail sendmail[18011]: k2RH75f9018011: from=<ionel@xxxxxxxxx>, size=1936, class=0, nrcpts=1, msgid=<000001c651c0$ca70ab30$5abfa8c0@hwg48>, proto=ESMTP, daemon=MTA, relay=myrelay.net [193.111.201.133] Mar 27 18:07:07 mail sendmail[18011]: k2RH75f9018011: to=<bulkemail@xxxxxxxxxxxx>, delay=00:00:01, mailer=esmtp, pri=31936, stat=queued Mar 27 18:07:28 mail sendmail[18310]: k2RH75f9018011: SYSERR(root): mydomain.net. config error: mail loops back to me (MX problem?)

The message is spam being sent to an invalid address. Other invalid addresses are treated better - I get "no such user here" in the log, but also "stat=Local configuration error". Any pointers much appreciated. Getting smtp auth with plain text to work would be great too! -- fedora-legacy-list@xxxxxxxxxx https://www.redhat.com/mailman/listinfo/fedora-legacy-list
