I am not going to reinstall the system. Maybe I just lack the sense of
humour but I certanly can't notice the anecdotal part of my affirmations.

I said the default FreeBSD filesystem which comes with the default
install is not suitable for a great number of Maildir mailboxes. I also
said I experienced problems with a total number of mailboxes lower then
1000. (shared webhosting)

I don't remember the size of /var, and this matters too.

Example of problem: entering a "ls" command in shell results in minutes
of delay before the output is displayed, on certain directories.
Messages like "running out of inodes", etc.

The OS was FreeBSD 4.x (4.5 to 4.11), with UFS1.

UFS1 and UFS2 behave the same about the issue I reported. This is a link
which briefly shows UFS1 and UFS2 differencies:

http://sixshooter.v6.thrupoint.net/jeroen/faq.html

However, never tried to practially reproduce this on UFS2.

The default /etc/fstab doesn't use noatime on spool directory. And that
would not solve the problem, it would just delay it a bit. (don't know
if even noticeable)
