Hi,

In order to pass PCI checking, we updated to MailEnable to 8.57 (Standard Version) and add two registry entry following the post http://www.mailenable.com/kb/Content/Ar ... D=me020583

[HKEY_LOCAL_MACHINE\SOFTWARE\Mail Enable\Mail Enable\Connectors\SMTP]
"Listen Port Authentication Mode"=dword:00000002
"Alternate Port Authentication Mode"=dword:00000002

But the SMTP server could not be connected by Outlook client. The error is:
Your server does not support the connection encryption type you have specified.
I have tried SSL and TLS, both are not working.

Any help is appreciated.

James
