I would like to start using SSL on an existing server. If I create a certificate with AMS and select "Explicit SSL" will existing clients still be able to log-in unsecured? As I understand it the choice to use SSL or not is then chosen by the settings in the client's e-mail software, is that correct?
How does this work with web mail? Is there anything that the client needs to do differently if we enable SSL?
Thanks,
Cam
