The emails seems to have to do with checking certificates.
So far, the most possible candidate is
It is on cmsdcam3 cmsdcam5 amd cmsdcam2.
It sends notification from root to email@example.com and firstname.lastname@example.org.
Don't know if it fix the problem. It does not address "expiring list2500Dirs" yet.
There are other similar cronjobs like this. Will fix them later.

These are actually general email, not particular to vulcan.
It has been traced deeper.
They are the emails from root sent to email@example.com.
firstname.lastname@example.org is decommissioned hence the mails were bounced back to root.
However, root forwards its mails to email@example.com.
This is how the mails appeared to be bounced to firstname.lastname@example.org.
It is not trivial to find the origin of the email.
In the end, /opt/poolQuota/cron/zz_checkticket.sh is the one (on cmssrv33 and cmsdcam5).
On cmssrv03, it is /opt/same/certificateAudit/zz_checkticket.sh.
Now the error emails have stopped.
Will watch it for a little while.
