[Dovecot] Problem with bodystructure/partial fetch using 1.1*

[mikkel at euro123.dk]

Hi there

I'm using dovecot-1.1b2/b3 with deliver. All information is stored in an
SQL database and no errors related to this issue are written to the logs
(actually I get no errors at all).

I've run into at problem; FETCH BODYSTRUCTURE is broken after upgrading to
dovecot 1.1b2 (same issue with 1.1b3).
BODUSTRUCTURE only returns information from the first section (with
incorrect content-type/disposition) and discards everything else.

This problem is somehow related to deliver;
IMAP returns the correct BODYSTRUCTURE for e-mails received before the
upgrade, but an incorrect for ones received after the upgrade.
This tells me that IMAP is working properly but somehow the MIME sections
are being corrupted doing mail delivery (if I fetch the complete body
nothing seems to be wrong).

Also if I fetch a section something is not right - instead of just the
section I get part of the Content-type header as well (but only half the
header).

Obviously this makes various webmail clients go somewhat crazy while
Outlook/Thunderbirds don’t mind (since they fetch the complete body and do
the MIME parsing themselves).

These are my compile options (GCC 3.4.3 on Solaris 10):
CPPFLAGS=-I/opt/pkgsrc/pkg/include/mysql
LDFLAGS=-L/opt/pkgsrc/pkg/lib/mysql ./configure
--prefix=/opt/freeware/dovecot-1.1b2 --with-pop3d --with-deliver
--with-mysql --with-prefetch-userdb --with-sql --with-gnu-ld --with-ssl=no
--enable-header-install
make; make install

Everything else works flawlessly.

Have anyone else experienced at problem like this?


Best wishes, Mikkel
