mh-redist-full-contents-flag is a variable defined in `mh-e.el'.
Its value is

nil

Documentation:
*Non-nil means the "dist" command needs entire letter for redistribution.

This option must be turned on if "dist" requires the whole
letter for redistribution, which is the case if "send" is
compiled with the BERK option (which many people abhor). If you
find that MH will not allow you to redistribute a message that
has been redistributed before, turn off this option.

You can customize this variable.

This variable was introduced, or its default value was changed, in version 8.0 of the MH-E package that is part of Emacs 22.1.
