You want option that is not secure when implemented incorrectly.

I think, you can't do that as plugin. There are no hooks in delivery class.

it should be implemented in 1.4.5cvs within two weeks, if stable team
accepts the patch. Header won't be removed if $edit_identity is set to
true. If admin understands the risk of message forging, he or she can use
The Force and modify squirrelmail source. Option will warn about forging
and indicate file that has to be modified.
