postfix not starting

[Bill Smith]

This is a newly installed stable machine, cvsupped and rebuilt this weekend.
I have installed postfix with amavisd-new and clamav.
They are all set for startup in /etc/rc.conf and sendmail is appropriately marked out, I have set up quite a few of these in the recent past.
However neither amavis, clamav or postfix start automatically, they can all be started manually.
I have turned on rc_debug, but they are not mentioned at all, their scripts are all in /usr/local/etc/rc.d. The only script mentioned in the debug output is fetchmail, which is not enabled in the rc.conf.
They are all freshly install from ports.
Where can I start looking to get this running?
