hi,
I am configuring a postfix-based mailserver at home, using the
docker-based mailserver
https://github.com/docker-mailserver/docker-mailserver
Under the hood the version is:
# postconf mail_version
mail_version = 3.5.17
I am trying to use a cidr table to whitelist. But contrary to what I
assumed it seems to read the ascii file, not the db file postmap makes.
Can people perhaps confirm that is how it should be?
Confirmed. Did you notice that the command
postmap cidr:/etc/postfix/client_checks
terminates with a fatal error?
postmap: fatal: no 'map create' support for this type: cidr

thanks! Glad to know.
As for your last lines: postmap without the cidr works fine to create a
db file, and in the manfile I could find no directions here (there is a
little line in man cidr, but I couldnt understand it enough to be helpful).
Given the not very helpful howto's on internet, it could perhaps help
if postmap --help would give some directions. Or a short line in the
manpage of postmap or the cidr manpage that the CIDR file is just plain
ascii

On the internet howto's are sometimes just wrong or give no answer. So
perhaps my erroneous assumption is made more often. See these howto's
for illustration:
