Postfix removes text/html part from mail client Outlook 2007
I have a strange problem. It seems Postfix removes text/html part from some mail generated from Outlook 2007. But not all the mails to this mail server have the same problem; only for certain accounts. The same mail sent to another account infact is OK. I try to use different MTA but the proble is the same. I don't know where to look for.
Debian Etch with kernel 2.6.8-3
Thanks for every suggests
