Was working well. Began trying to add profiles and could not seem to get that done. Gave up that attempt for now and thought all was well, until I went to send an email late Friday Nov 6, 26. Was challenged for SMTP password. None of the ones I tried seemed to work. The target SMTP machine is local, same subnet, postfix.
Using a backup Laptop as I feared my usual PC, Windows 10, might have been compromised and has been shutdown.
I'm at a loss. Other than change passwords on several machines, what are my options?
