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.
