Bug#1009617: mailscripts: new script to reinject a message via sendmail: sendmail-reinject
Package: mailscripts
Version: 0.24-1
Severity: wishlist
Tags: patch
Attached is a patch (via git format-patch) for a script to re-inject
an existing message via sendmail. The script extracts the sender and
all recipients from the message and constructs the appropriate
sendmail command to re-send the message. This is very useful for
messages that were fcc'd but for some reason failed to make it out on
an initial pass (e.g. MTA misconfiguration). A man page is also
included.
Thanks for the useful package!
jamie.

Thanks Sean. --notmuch-id seems ok to me. Do you want to go ahead and make the change, or should I resend the patch? jamie.

Subject: [PATCH] new script to reinject message via sendmail
This script simply takes an existing mail file, parses it for sender
and all recipients, and constructs an appropriate sendmail command to
resend the message.
It requires the sendmail binary at runtime, and the notmuch python
library in order to extract the message from an existing notmuch
store.
