Quick notes on running Rspamd in a Podman pod

This includes three containers:

Rspamd itself, for use as a Postfix milter
redis
unbound (because rspamd's DNSBL lookups will likely fail when using public or your provider's DNS, see https://www.rspamd.com/doc/faq.html#resolver-setup).

Ideally, all of this should work in both rootless and rootful mode.

	# quickly create large/very populated zip files for testing purposes, without taking up lots of disk space

	dd if=/dev/zero bs=1m count=10k \| zip -9 single-10g-file.zip -

	dd if=/dev/urandom bs=1 count=20000 \| split -b 1 -a 4 - test_ && zip -q -m 20k-tiny-files.zip test_*

	# this ensures CD entries with the LFH offset in the ZIP64 EIEF:
	dd if=/dev/zero bs=1g count=6 \| split -b 2g - test_ && zip -0 -m few-huge-files.zip test_*
