# Standard-violations detected in the wild during development of mblaze
This list is probably not complete.
* RFC5322 assumes CRLF line endings throughout, but Maildir messages
are generally using Unix line endings. mblaze accepts both, and
only uses CRLF when required (e.g. for signing).
* Backslashes in atoms (RFC 5322, 3.2.3) are parsed as if they were
inside quoted strings.
* Return-path is accepted without angle-addr (RFC5322, 3.6.7).
* Encoded words within quoted strings (RFC2047, 5.3) are decoded for
header printing.
* Encoded words within MIME parameters (RFC2047, 5.3) are NOT decoded.
* Empty encoded words are decoded as empty string (RFC2047, 2).
* Split multi-octet characters between encoded words (RFC2047, 5.3)
are reassembled if the encodings agree.
* Date parsing is strict, obsolete timezone and two-digit years are
not parsed (RFC5322, 4.3).
* Mails without MIME-Version (RFC2045, 4) are still subject to
MIME decoding if the Content-Transfer-Encoding header is present.
