Error messages

When I try and send an email I frequently get error messages

  1. Add security exception. The Location adds the port number to the address.
  2. When I remove the port number it then tells me that the site has a valid, verified address.
    3.I then get a message Send message error “An additional policy constraint failed when validating this certificate.
    The configuration related to must be corrected.”

This has only started in the last couple of weeks. I have checked the outgoing server settings etc and they seem OK.

Try disabling email scanning in your anti virus. That usually fixes the problem.
