697376 - Incorrect parsing of Message-Id header with CFWS (Comments, Folding, Whitespace)

Status: REOPENED

(Thunderbird :: Folder and Message Lists, defect)

Description

[Alexander Galanin]

Attachment: msg1.eml (parent message)

Relation between messages msg1.eml (parent) and msg2.eml (child) is not detected in the threaded view.

I think that reason is incorrectly handling of Message-Id header with comment field. Let's see at the header of msg1.eml:

    Message-ID: <1319452010.3981.1.camel@krishna> (sfid-20111024_142558_138515_6F63A54F)

Comment was added by CRM114 mailreaver and AFAIK does not violates RFC 5322 because Message-Id header defined by the following grammar:
   message-id      =   "Message-ID:" msg-id CRLF
   in-reply-to     =   "In-Reply-To:" 1*msg-id CRLF
   references      =   "References:" 1*msg-id CRLF
   msg-id          =   [CFWS] "<" id-left "@" id-right ">" [CFWS]
   id-left         =   dot-atom-text / obs-id-left
   id-right        =   dot-atom-text / no-fold-literal / obs-id-right
   no-fold-literal =   "[" *dtext "]"

confirming based on RFC 5322 - there are a lot of places where we don't handle CFWS, from what I can tell.

I disagree with closing this bug. This bug is older and contains more information than #1259430.
