Problem with mail structure from messages

[Sylvain MEDEOT]

Hi,

Since a few days, mails I'm receiving from gmail or yahoo have a bad structure once in my
kolab mailboxes :

The clients (thunderbird) are not able to decode the mail structure...

Here is what I get in thunderbird :
------=_Part_28582_7948865.1192289535205
Content-Type: text/plain; charset=ISO-8859-1
Content-Transfer-Encoding: quoted-printable
Content-Disposition: inline

D=E9sespoir

After further investigation, I pushed the mails directly to a standard postfix
installation (no kolab) and all is perfectly fine.

Here is a copy of the mail in kolab :

>From what I see, the "Content-Type: multipart/alternative; " is missing in the kolab mail.
What can break the message in kolab ?

Any help welcome,

Regards,
