Here's a condensed version of the run script from:

http://www-dt.e-technik.uni-dortmund.de/~ma/postfix/daemontools.html                                                               

Notes:

    - the postfix 'master' process needs to run under a process supervisor

---
#!/bin/sh -e

export PATH=$(postconf -h command_directory):$(postconf -h daemon_directory):${PATH}

master -t || postfix stop 
postfix check 
exec master  >/dev/null 2>&1

Those bits are likely unwise. Throwing away error output is always a bad 
idea.

Agreed. Here's a better version:

--- 
#!/bin/sh -e

export PATH=$(postconf -h command_directory):$(postconf -h daemon_directory):${PATH}

master -t || postfix stop 
postfix check 
exec master 

# Notes:
#
#  - use ksh for versions of sh that don't support $()
#
#  - master does a setsid(). This will fail if it already is a process leader ;
#  if it is run from a shell 
#
#  - postfix is not intended to run from daemotools, and as such "postfix stop"
#  no longer works as intended by the author.
