I think RFC 822 says that ; should be escaped.
atom = 1*<any CHAR except specials, SPACE and CTLs>
; being a special
However my point was simply that it's an introduced ; that Exim doesn't
ship with and has caused my customers greif. Changing the ; to ,:/ or
making it look more like another comment in the line (Mailer=Exim
OS=FreeBSD).
Maybe breaking old versions of Outlook 2000 and Express 5 is enough
reason for some people to WANT ; in Received:. At my location we
simply change the ; to : in the Makefile to make everything works as
expected.
