[Linux-disciples] Modifying headers of outbound msgs in postfix

[Stephen R Laniel]

I'm going to be hosting a friend's company's website, and
I'll also be setting up a few email addresses for them.
Those email addresses will all forward to the home email
addresses of people within the company. To avoid confusion
on the other end, I'd like to change the subject line of
messages destined for those email addresses so that they
look something like

	Subject: [companyName] [old subject]

If the message were coming to a local shell account, I'd use
Postfix for this. If the recipient were a mailing list, we'd
get the '[companyName]' prefix for free. But what if the
receipient is in /etc/aliases and nowhere else?

Presumably I can get Postfix to do this. But having done no
Postfix admin before now, I'm not sure how to do it. Can the
more Postfix-aware among you help me out?
