Good morning Anthony. As I said before, the settings I stated fixed a
user's problem who had a specific configuration using Eudora. What we have
found it that this problem is occurring with different types of
configurations, and with different clients also. If you would like, you may
e-mail me using the form at http://askatech.ipswitch.com. You may put it to
my attention in the body of your problem. This way I can record your
configurations and try to help you. Thank you Anthony, and I'll look for
your e-mail.
