Hi,
I ran into a problem wherein my mail client (RoundCube) would not
display a message from a Dovecot IMAP server (claiming that the message
had no content). The raw source of the message looked fine, but the body
structure returned by Dovecot only had the first text/plain part and not
the alternative text/html part. The message looks like:
... headers removed ...
X-Mailer: Lotus Notes Release 6.5.1 January 21, 2004

Content-Type: multipart/alternative; boundary="=_alternative

This is a multipart message in MIME format.
--=_alternative 006F3A73872574E8_=
Content-Transfer-Encoding: 7bit
Content-Type: text/plain;

blah blah blah

Content-Type: text/html;
charset=us-ascii
<br><font size=2 face="sans-serif">blah blah blah in HTML</font>
--=_alternative 006F3A73872574E8_=--
I did a little bit of tracing through the parsing code
(message-header-parser.c:message_parse_header_next()) and it appeared
that the boundary in the Content-Type header was not parsed correctly,
evidently because the header line was folded in the middle of the
boundary string. RFC 822 appears to allow folding in a quoted string
like this (ยง3.3 "quoted-string"), so I'm curious whether the parsing is
working correctly.
Thanks for your help!
Here is my Dovecot information:

"dovecot -n" output:
