as Postfix condenses multiple CR followed by LF into a single CRLF: https://marc.info/?l=postfix-users&m=170456217431710&w=2
So this works even with patched Postfix and smtpd_forbid_bare_newline=yes.
smtpd_forbid_bare_newline=yes
Btw this is now fixed in Postfix 3.9 prerelease 20240106 (and will be in upcoming 3.5..3.8 patch releases)
I see, I just reverted it!
