Is there any filtering in postfix, like amavis, spamassassin?

nope.

And problem resolved.

On the 1st, the damned DHCP lease had failed again due to the mysterious time drift issues I have been tracking down in another thread.

But I needed this system up so I launched nmtui and set a static IP.... Wait for it.. to 10.201.1.12/32

/fucking sigh....

I also enabled the Time Synchronization in Hyper-V on March 1st. As soon as I fixed the /32, this morning, the Hyper-V integration started fixing the time every 5 seconds.. screw that. Turned it back off. I will count on chronyd it works well as long as the IP stays online.

I really want to figure out what is causing these VM's to do that. it is not normal.

This problem was caused by me not being careful enough when I changed something to avoid the DHCP problem.

And there goes a successful mail test.
