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 smtp.xxxx.com 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.
