+# 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).
