When forwarding an email, how do we remove the prefix character, attached
to the front of each line of the quoted email, without changing the prefix
configuration? Isn't there a way to remove just the column of prefixes?
Alternatively, is there a way to resubmit the email, so it appears as an
original, versus forwarding the email? All we want to do is send the same
email, with a few changes, to another distribution group as if it were an
original.
