A sample proxsmtpd.conf has been copied to /etc. Edit it to suit your 
needs.

I you intend to use it in transparent mode then add a rule along these 
lines to pf.conf:

pass in on $int_if inet proto tcp from any to any port 25 \
	rdr-to 127.0.0.1 port 10025

where $int_if is your internal firewall interface.

${PREFIX}/share/examples/proxsmtpd contains some examples of custom
filters.
