Microsoft exchange server 2007 and popcon 3.60

I have Microsoft exchange server 2007 mailing system with popcon pulling the data and transferring to exchange server.
After popcon pulls all the data
Now I am getting error message "mail transfer to M.S Exchange server  failed.Exchange retuurned follwoing error message after the data/end of mail marker :554.6.0. Invalid message content.

One of the message has a problem.If I remove  the msg ,then it becomes okay.There are 100s of emails ,it becomes very difficult to track the problem.

Is there a particular reason you are using POPCON as opposed to having mail delivered directly to your server?

Exchange is designed to have mail delivered to it rather than you pulling it in.

I do not static ip.I have a dynamic ip which is hosted outside our ofiice.That is why using popcon.
