I did a bit of Googling to no avail, I wonder if anyone in the community has come across the same hassle I'm experiencing recently, I've had Norton Anti-virus installed on my rig now for about +- 2 weeks now and recently have noticed that majority of the time I get an error when downloading mail and later on when I leave it the mail will be downloaded, but when sending mail to clients they receive a bunch of random lettering. I have discovered that when I disable the scanning of incoming and outgoing email they are delivered correctly as well as all my mail sitting on the server is downloaded.
I am running Windows 7, and Office Outlook 2007.
