there's a bunch of active work on this, by many of the same people, so I wanted to quickly ask
the repoze 4.x branch seems to break the encoding imports for pyramid_mailer . if this is being worked on right now, i'll watch this repo more closely to integrate support for the send_sendmail functions that repoze.sendmail accepted from me. ( it's probably all done, i just can't test and need to finish the tests ).
I don't know the answer to this but let's take this to some mailing list somewhere (maybe repoze-dev). Its not an issue for the issue tracker.
