Looking at this... unfortunately it does look like we are
incorrectly generating the quoted-printable data. To preserve
whitespace at the end of a line, it must be followed by a "soft line
break" - a bare "=". This isn't happening here. It looks like the
quoted-printable decoder used by Cyrus (I can also confirm the same
behavior on Dovecot 2.2) is much stricter about the format than our
encoder.
We are using PHP's built-in quoted-printable stream encoder to
produce this output so this (unfortunately) might be an issue
outside of the realm of Horde/IMP. I will need to investigate
further.
...and it is a PHP bug.
