Fwd: Best way to configure TLS in Cyrus

[Jean-Gabriel Duquesnoy]

Hi,

I have been operating a mailserver using Postfix and Cyrus
successfully for some time now. But it was only for internal use
(within the intranet) so no specific encryption was necessary.
No I want to allow the users to access the mailserver also from
outside the intranet, and need to improve the security.
What is the best way to do that? Use TLS as encryption as well as
authentication? How is the best way to implement/configure this?
Any help would be greatly appreciated.

Best regards,
