Comment 9 for bug 1916541

Thanks Paride,
I am glad that you could reproduce it, and it's not like either I or my system is crazy :)

I noticed something that may or may not be relevant. I have another machine with hirsute, that was purchased a year+ ago and has undergone less package upgrades: mail delivery _worked_ there. I did _not_ reconfigure it as "satellite" and I don't remember how it was configured at the start, probably as all default.

The difference that I noticed is that the contents of /var/spool/postfix/usr/lib (as filled by posttix's startup procedure) is significantly different. One wild speculation would be that some shared lib there is opportunistically loaded that refers to an earlier glibc version, and that subsequently somehow results in impossibility to load nss libraries.
