Mail Server With Both Postfix And Sendmail Installed, Active MTA Gets Switched.
Ok, so a bit of a long subject line there…
I’m running an email server using postfix, but a critical third-party package being used requires ‘sendmail’ the package.

Run “systemctl mask sendmail” as well. That should permanently disable the service.
You could look for any package that refers to sendmail in a script or trigger:
rpm -qa | while read pkg do
rpm -q –scripts –triggers “$pkg” | grep -q sendmail && echo “$pkg”
done
If the problem is a trigger on the sendmail package, it could run without any changes to the sendmail package itself.
Worthwhile thing to do; still curious about what caused it, but if this will lock it out…..
Ah, yes, indeed. Only three packages are output: sendmail itself, postfix, and the third party software; postfix did get an update recently, and after checking to see I didn’t reboot after that update.
