Ben,
This section from 822 should help answer all of your questions:
"Some characters are reserved for special interpretation, such
as delimiting lexical tokens. To permit use of these charac-
ters as uninterpreted data, a quoting mechanism is provided.
To quote a character, precede it with a backslash ("\").
This mechanism is not fully general. Characters may be quoted
only within a subset of the lexical constructs. In particu-
lar, quoting is limited to use within:
- quoted-string
- domain-literal
- comment
Within these constructs, quoting is REQUIRED for CR and "\"
and for the character(s) that delimit the token (e.g., "(" and
")" for a comment). However, quoting is PERMITTED for any
character."
Meaning that if any token character is sent and stored within the server,
it then *should* be quoted (escaped) by the server when sending its
response to the receiving client if it is contained in a response that uses
the same tokens.
So in your examples, if Outlook requests the envelope for the specified
message, then the server *should* quote the parenthesis and the comma (as
well as the double-quotes themselves *if* they are stored on the server in
that manner) and Outlook should handle this accordingly, and at the very
least NOT choke on the message.
AFAIK, there are no knowledge base articles on this, although I havn't
searched very hard for it.
Chris
