I`ve found this on the CyberSitter Web site, could this be my problem! Is this what`s happening with the internet mail scanner?
Q CYBERsitter is still filtering my email. Why?
--------------------------------------------------------------------------------
A This problem can occur when you are using Outlook or Outlook Express with Norton AntiVirus (NAV) E-mail Protection enabled. NAV uses a POP3 proxy server on your computer to route all incoming mail through to check for virus attachments. Setting CYBERsitter to ignore e-mail forces it to ignore filtering on ports 110 and 25, the standard e-mail ports. NAV re-routes your e-mail using a random port other than the ones CYBERsitter is ignoring. This causes your e-mail to be filtered. Because the ports NAV selects appear to be random, it is not possible to add additional ports to exclude.
The solution for the time being is to disable NAV e-mail checking. We are working on a better solution, but have not found one as yet. NAV will still detect viruses in attachments as they are saved to disk, read, or executed (the three ways to infect a system), so the effect on your virus protection will be minimal.
Thanks
