[Pkg-mailman-hackers] Quotes inside or outside (was: Bug#638994)

[Etienne Millon]

Hello mailman hackers,

I'd like to have your input about a bug that was reported against
rss2email (#638994, Cc'ed with the participants).

The problem here is that it is unclear in what order quotations should
be applied (double quotes "" and =?utf-8?q?...?= ). Here are the two
possibilities :

  (1) From: =?utf-8?q?Poradnia_J=C4=99zykowa_PWN?= <nobody+rss at jwilk.net>   
  (2) From: "=?utf-8?q?Poradnia_J=C4=99zykowa_PWN?=" <nobody+rss at jwilk.net>  

(1) is what used to be generated by rss2email, and the question is
whether (2) should be used instead.

It seems from #638994 that mailman does not interpret correctly (1),
but accepts (2), which is forbidden according to RFC2047 (relevant
sections quoted in the bug discussion).

Do you think it could be a bug in mailman ?

(Furthermore, if the problem is on rss2email's side, I would argue
that it's in fact a bug in python's email lib)

Thanks a lot in advance,
