Mail-exchange with other mailprovider secure? (mailserver to mailserver)

[Thomas Becker]

Hello,
when I'm sending or receiving messages with my mailclient I can use SSL/TSL to secure the communication (mailclient to server).

How does Plesk (Postfix) secure the mailexchange with other mailservers?
How can I check if the communication is secure (mailserver to mailserver)?

Thanks.

Hello Thomas,

Please take a look at the following page of the Parallels Plesk Panel 9.2 Administrator's Guide:

Installing Custom SSL Certificates for Qmail or Courier-IMAP Mail Servers

Thanks Denis.

I'm a Linux/Unix newbie. I think ther is running Postfix as MTA on my vServer.
In mailheader you can read something about Postfix.

Is it possible to secure the mail-communication between mailservers with the default Plesk certificate?
Because certificates are expensive.

Is there a way to check if the communication is secured?

Thanks.
