Re-sending selected e-mail messages

I need a way to automatically re-sent stored e-mail messages
according to some criteria and like to ask for advice or
suggestions for an already existing solution before I start
reinventing the wheel. :-)

The messages in question are stored in MH format. This is a
tree where a mailbox equals a directory, and the individual
files in that directory equal the messages. They are numbered
1, 2, 3, 4, ..., and so on. Each message is in

	Content-Type: text/plain; charset=ISO-8859-1
	Content-Transfer-Encoding: quoted-printable


	Content-Type: text/plain; charset=US-ASCII
	Content-Transfer-Encoding: 7bit

or maybe even

	Content-Type: text/plain; charset=UTF-8
	Content-Transfer-Encoding: 8bit

text format. Some of them might contain an attachment, which
is "included" in the file with something like

	Content-Type: ...;
	Content-Disposition: attachment;
	Content-Transfer-Encoding: base64

Some messages are "fully multipart".

So when iterating on ~/Mail/sent/1,2,3,4,5,... I get all the
messages. Each third line, "To:", is the criteria to look at.
If it matches a given recipient, the mail should be sent again.
This can easily be done by the system's mailer which is properly
configured (and uses ISP's MX), so | mail -s "maybe new subject"
is possible. The message should already be properly pre-composed.

What is the easiest way to do this without reinventing the wheel,
or should I? :-)
