Our IT security guys just asked me to remove/sanitize a message that I posted on the openSUSE mailing list back in 2017. How they came across this message is mysterious. But I did post some stuff about the company ADS that I was trying to access from openSUSE/samba. I don't remember the specific details of the problem, and I do not think it was ever solved. No matter. I thought I was usually pretty careful about sensitive details in posts. Seems not always...

Is it possible to remove messages that were posted? As it provides no solution and is rather old, I cannot see that it is especially useful anyway.
