This is Zammad version 2.4.x from docker-compose
We seem to attract junk in our address book/user list, ie someone will email
validaddress@here.com and then cc
doesntexist@here.com
we end up with doesntexist@here.com in our zammad user list which then popups up as an auto-complete suggestion when emailing someone from within zammad, ie in the To: field as you start typing an address it might give doesntexist@here.com as a suggestion to auto-complete.
Deleting only removes it until the next time it gets added back, marking it inactive doesn’t stop it appearing as a suggestion either.
Is there a way to keep it in the user list but make it not show in the suggested auto-complete list?
