$ postconf mailbox_command
mailbox_command = /usr/local/bin/maildrop -d ${USER}

(postifx shipped by macos, but own LaunchDaemon(s), also 
clamdscan)

Which is why I naively tried to set the environment in my 
maildrop mailfilter in my equally naive understanding of the 
first paragraph of the SECURITY section in man 1 maildrop.

Again naively, I also temporarily uninstalled bogofilter from 
/usr/local and installed it at $HOME. Works fine, but also 
ignores BOGOFILTER_DIR.

Anyway, it's nothing urgent, I can make everything work via 
configuration files. I was just curious.
