Dear Maintainer, The rfc2047_parameters option is not particularly easy to discover in the manpage and/or figure out it may help for the particular issue it is meant to fix. See this thread on debian-user for an example. https://lists.debian.org/debian-user/2020/03/msg00886.html I would kindly suggest it is enabled by default as it doesn't affect the correct case and helps a lot with mail sent by buggy clients. Kind regards, Andrei
The manpages says: ----%<---------%<----- ----%<----- Note that this use of RFC2047's encoding is explicitly prohibited by the standard, but nevertheless encountered in the wild and produced by, e.g., Outlook ----%<---------%<----- ----%<----- Not sure if it should be set to true by default,.. let's try to check why it is explicitly prohibited.
