This is good so far. But one thing to remember is that any command run
during startup is going to run as root, rather than user. I've no
idea if clawsmail cares, but you can fix this by prefixing the command
with 'su user -l -c', for example:

su user -l -c  "/usr/bin/whateverclawsmailis --options --if --necessary"

Urr. Among other issues, this stands a fair chance of being overwritten
on upgrades.

A more standard unixy way to do this is to add a seperate startup file.

1. Create the file "/etc/init.d/clawsmail". While the following is
not really a complete init.d script, I think it's sufficient for your 

export PATH
set -e
case "$1" in
		su user - -c "/usr/bin/clawsmail --whatever"
		echo "only starts clawsmail"
exit 0

2. Make the file executable:

	chmod a+x /etc/init.d/clawsmail

2a. Test the script (from an xterm on the device!):

	/etc/init.d/clawsmail start

3. Make the file callable during startup:

	update-rc.d clawsmail defaults 99 01

This last command creates links in the various /etc/rc[1-6].d
directories; the '99' makes sure it's run near the end of startup.

To stop the startup, just remove the links:

	update-rc.d -f clawsmail remove

The advantages of this over the original solution:

1. You're not editing a critical system file.

2. You're changes won't be overwritten. (Well, maybe not during a flash.
Does the "backup/restore" procedure save the contents of /etc/init.d and
the links?)

3. This is where every experienced Linux person will expect to find
startup stuff.
