Email Gateway 6.7.2 has an SMTPI configuration option called Minimum Cipher Required. You can select: none, low, medium, or high.
But I can find no documentation on what you get when you select low, medium, or high.
What do low, medium and high actually select / change on the back end configuration?
In the administrator's manual, it says the default option is "EXPORT", which is not even an option.
