Cough - does that mean that the mail system will reject it as having been already received? Does it have the same message- id (or something like that) as the original message even though I have edited the contents?
It is possible that your mail client doesn't update the message-id and it is possible (maybe even valid) that some server would ignore it. Some versions of Mailman definitely do funny things with bad Message-IDs. Maybe you can test this by sending a mail to yourself, then "send again" it to yourself and see whether it changed the ID (or if it arrives at all!).
