First of all, you are looking at the wrong RFC. RFC-821 is the one you
"'" is not a "special" in RFC-821.
It is generally useful to mention what mailer and version gave the above
error. As I recall, the "this is abnormal, investigate" normally
translates to "help, my sysadmin has broken me".
I don't know how more graceful Zmailer (btw, Zmail is something
completely different) could handle this. There are so many broken mailers
out there right now: some by bad configuration, some by bad design (one NT
mailer that doesnt' accept "MAIL FROM:<>" comes to mind).
