Re: RFC 5321 VRFY and quoting syntax

If there's no further input, I'll go for the errata. Murray - can I take 
you up on your offer to help with the process?

To summarize:


1. Update the paragraph in section 4.1.2 regarding the use of the 
backslash to explicitly mention it applies only when used in a 
quoted-string.

2. Section 3.5.2 claims the responses from a VRFY or EXPN request must 
include the mailbox name using a "<local-part@domain>" construction - 
this both contradicts section 3.5.1 (which allows a response without the 
pointed brackets), and doesn't make sense on it's own since a 252 
response might not even have anything to return.

and optionally:

3. Seciton 3.5.1 can specify that in particular, using pointed brackets 
without quotes (as is used in MAIL and RCPT commands) is not valid here, 
since this seems to be a common mistake and the wording leaves room for 
confusion (although the ABNF is correct).
