Indeed that's a bug. I gather that you're saying that this bug is not the cause of the OP's problem, though? > The Subject: header above is non-compliant in two respects. It is too > long.

Anyway, IIRC the length limit is a SHOULD NOT, not a MUST NOT, right? > real problem is item (1) in section 5 of the RFC says in part: > > Ordinary ASCII text and 'encoded-word's may appear together in the > same header field.

Agreed, but I think that by default[1] email should try to parse this header as the user intended it. It's not like encoded-words are that easy to confuse with intended text; it's unlikely that changing 'linear-white-space' above to 'linear-white-space or specials' would harm anyone. > This is a problem with the MUA (mail client) that encoded the Subject: > header in the first place. Agreed, but I think following the Postel Principle here is likely to do less harm than adhering strictly to the RFC. That said, I'm not in a position to contribute code, and this is a pretty invasive change, so the user is unlikely to see a version of Mailman that handles this any time soon. They are likely to have more luck switching clients. Footnotes: [1] Ie, there should be an option to be strict. ------------------------------------------------------ Mailman-Users mailing list Mailman-Users@python.org http://mail.python.org/mailman/listinfo/mailman-users Mailman FAQ: http://wiki.list.org/x/AgA3 Searchable Archives: http://www.mail-archive.com/mailman-users%40python.org/ Unsubscribe: http://mail.python.org/mailman/options/mailman-users/archive%40jab.org Security Policy: http://wiki.list.org/x/QIA9
