A lot of mail that is not spam when it arrives WILL be spam when it is forwarded as it will fail SPF, Fail DKIM, and any header checks will flag the mail as suspicious.
The only way to safely forward mail is to enclose it as an attachment, and this is something users do not want.
IMO this is wrong. A classic forwarding (e.g. by .forward or by a MLM that does not alter Subject and/or body) will *not* break DKIM. Therefore it will pass e.g. DMARC...
Just have a look at the postfix-users mailing list as a good example...
Just my 2ยข.
