Have a couple quick questions regarding quoted local-part addresses. I
realize this is the 822 group but this is affecting our MTA on both the RFC
821 MAIL FROM/RCPT TO and the 822 headers.
Our engineers have been over the RFCs 821, 822, 2821 and 2822 and had some
questions -- I thought I'd pass the questions along because -- well -- I'd
like to get this right ;)
1. Are quotes taken as literal delimiters in comments? E.g.
Joe(A comment ")" here)User(_at_)arrgh(_dot_)org
2. Is there such a thing as a comment in a literal such that the comment
gets
stripped?
"Joe(The Thug) User"@arrgh.org
3. Should comments be omitted in any 821/2821 envelope? Is it better just
to pass through quoted stuff completely untouched? Should a quote char '\'
be stripped out when found - or just passed on?
4. We've run into a particular MTA that does not escape commas in quoted
local-parts which appear to be contrary to at least RFC 2822. E.g.
"8379,39082"@domain.com It seems prudent to accept this as is and
continue on.
