We are in the process of migrating to a new Exchange 2007 (SBS 2008) from Exchange 2003 (SBS 2003). We currently receive automated reports to a mailbox on the Exchange 2003 server from an external source, and then have an internal application server download the emails (via POP3) and manipulate the email content.
The application server vendor has alerted us that Exchange 2007 will break this system unless the content type of the emails received can remain as single part messages with content-type text/html instead of being converted to multi-part quoted-printable which I understand is the default.
So my question: is it possible to change the content type on an Exchange 2007 server? Ideally, for a single mailbox? I've seen work-arounds involving other SMTP servers, but I would like to avoid that if possible.
