TwitterDoes anybody know, when Postfix on Plesk 10 relays mail to other servers, is the text body encrypted?
For example:
Sender's Laptop -> Sender's Server -> Recipient's Server -> Recipient's Laptop
1. Sender's Laptop -> Sender's Server
This goes from the Sender's Laptop via SSL/TLS to the Sender's Server. The email is safely encrypted during transmission, and exists only temporarily on the server in plain text (assume that Sent mail is saved on peoples' laptops, not the server).
2. Sender's Server -> Recipient's Server
In this step, is the email encrypted?
Secondly:
In my logs of Sender's Server -> Recipient's Server, I have this in the logs:
"certificate verification failed for [subdomain of Recipient's Server] untrusted issuer [details of issuer]"
Did it go ahead and transmit the message encrypted using the unverified certificate or did it just transmit in plain text?
