I have had updates twice now switch the active MTA to sendmail, and I have to manually 'systemctl disable sendmail; systemctl stop sendmail' and 'systemctl enable postfix;systemctl start postfix' afterwards.
Run "systemctl mask sendmail" as well. That should permanently disable the service.
I am trying to find out what package update caused this to switch; or which logfile to look at to show me the systemctl messages that show the enable/disable sequence and points me to the correct package to file the bug against.
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
Sendmail hasn't had updated packages in a long time, since August 2017. None of the package scriptlets from the above packages look like they would affect the sendmail setup. So, I'm looking for suggestions on where to start looking for the data to ferret this out; no clues are in /var/log/messages or /var/log/yum.log.
If the problem is a trigger on the sendmail package, it could run without any changes to the sendmail package itself.
