It will use spamd-sync (udp port 8025)

-K is optional. BUt if you use it, all instances syncing should use
the same key.

It's symmetrical. All spamd's send updates to each other. No tcp
involved, only udp. Specify A's IP on B and vice-versa.

It uses a sha1 hmac message authentication code, so no md5 digest.

Never used -M myself, but reading spamd.conf it looks like you only
specify an -M IP on the host serving that IP. Note that -M is
optional.
