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?
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
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.
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).
