Here is what I have so far:

divert(-1)dnl
include(`../m4/cf.m4')
VERSIONID(`20070322.001')
OSTYPE(bsd4.4)dnl
GENERICS_DOMAIN(escape.goid.lan escape)
FEATURE(genericstable)dnl
FEATURE(masquerade_envelope)dnl
define(SMART_HOST,smtp:mail.widomaker.com)
FEATURE(redirect)dnl
FEATURE(nocanonify)dnl
FEATURE(`accept_unresolvable_domains')dnl
FEATURE(`accept_unqualified_senders')dnl
define(`SMTP_MAILER_FLAGS',`e')dnl
define(`confCON_EXPENSIVE',`True')dnl
define(`confTO_QUEUEWARN', `4h')dnl
define(`PROCMAIL_MAILER_PATH', /usr/pkg/bin/procmail)dnl
FEATURE(local_procmail)dnl
MAILER(procmail)dnl

dnl # The following two mailers must always be defined
MAILER(local)dnl

It mostly works.

Problems:

I cannot send mail from my mail server.  It tries to relay through my ISP
smart host which times out, and then through my ISP's backup smart host,
which also times out.

Client machines can relay through my mail server just fine.  It queues up the
mail for my ISP smart host, and it goes straight out with no trouble.

Obviously I have more work to go, and I'd like to eliminate the need for the
accept features.
