For sup-heliotrope/sup#205 the proposed fix was gauteh@2ee5086. The equivalent is yet incorporated on this fork.

Hi, can you provide a concrete test case containing the actual header that causes the issue?

[ZJvandeWeg]

I might have been to fast with this issue.
Will look into it this weekend again. Sorry for wasting your time.

Test message and tests for sup that currently fail are here: sup-heliotrope/sup#214

[gauteh]

An incorrect fix is here: sup-heliotrope#3

I tried feeding those messages to rmail and they are handled without issue, because rmail will not try to parse them. Even properly quoted non-ascii header values are returned as is with no parsing.

However the unquoted utf-8/latin1 data in header values will come back encoded as ASCII-8BIT, and that needs to be handled properly by whoever is using rmail.

In short, this does not look like something that can be fixed in rmail without breaking its API.

What about using the constants from here? https://github.com/mikel/mail/blob/dc0f89bb33722ec1e6fa404a34055fe6e0189651/lib/mail/constants.rb

This is quite an annoying bug. :-(
