The problem doing that is that some emails are rejected by
external.example.net mail servers because of SPF, for example :
"550 SPF Hard Fail: Following sender domain's SPF record v=spf1 [...]
-all does not designate a.b.c.d as permitted sender."

with mail forwarding.
forwarding without changing sender is broken and was since the beginning,
SPF just made it visible.
If you are forwarding to invalid address, the reports should go to you, not
to someone whose mail you have forwarded. They sent it to you, why should
they care that you decided to pass it further? It's your business now.
Maybe you should explain to your user that he/she can lose legitimate emails
if he/she is using mail account at such an incompetent provider.
maybe the OP should configure forwarding properly.
