Mail is back up and is now on a stable but slower platform.  I will need to reload Linux on the other machine as it has somehow become badly corrupted.  Systemd is not acting properly on the larger machine and is starting servi ces, particularly systemd-networkd which needs NOT to be running as I use network-manager, even though they are masked that breaks the network.  It’s not impossible that it has become infected with some sort of malware, though the last time I had machines with a confirmed virus was three decades ago.  But then there are those among us who consider systemd to be malware…  I have looked and can’t find anything but it is possible to disguise things as system processes, etc.  Given though that this happened right after a drive went south, it is more likely just corruption of something somewhere, maybe multiple somethings but then again our web server was recently the target of a denial of service attack so who knows.  Cleaning it out and starting fresh is the safest bet.
