I stopped Dovecot, backed up the tens of thousands of files in

at least not to Dovecot.
I also found the major problem consuming so much /var space was Void
Linux' package cache files, so I deleted all of those more than 3
months old. Soon I'll make a daemon or a cron job that deletes old
files in these two directories, and probably a lot more.
I'm not an expert on Dovecot, but I've run it for quite a number of
years, and cannot remember having seen that directory on any of my
installations.
So I guessed the easiest way to find out about it, is to Google for
"/var/spool/smtpd" (including quotes). The results seem to indicate
that the directory is related to OpenSMTPD. E.g.:
https://manpages.debian.org/stretch/opensmtpd/smtpd.conf.5.en.html
FILES
[...]
/var/spool/smtpd/
Spool directories for mail during processing.
So if you have OpenSMTPD installed, you probably deleted spool files
from undeliverable email (or so; I'm unfamiliar with OpenSMTPD). Maybe
you should check what is in those files (Postfix queue files are
readable when using `postcat`, maybe OpenSMTPD spool files are also
readable).
