Summary:                    dbmail break quoted printable headers
Description: 
dbmail breaks quoted printable subject header on delivery by wrong line
wrapping.

May be the bug is in gmime 2.4.

Each line of folded quoted printable encoded subject should be prefixed by
=?UTF-8?Q?

This only happens if there is no Return-Path header on the message during
delivery. DBMail adds such a header (fixes
http://dbmail.org/mantis/view.php?id=145) which should have been
done by the MTA - rfc2821, and that triggers the unexpected behaviour in
gmime.

I've contacted the gmime maintainer to see if we can solve this.

In the mean time: fix your MTA or add a Return-Path if you are manually
inserting messages without using an MTA.

---------------------------------------------------------------------- 
initial feedback from the gmime author indicates a broken utf7 encoded
header (no space before the encoded part)

the broken folding looks like a gmime bug alright.

we'll work on a workaround fix in both gmime and dbmail for this
