Does Salesforce allow encryption of outgoing mail or do I need to set up an email relay?

Best Answer chosen by Nancy J
Hi Nancy,
Due to some vulnerability issue Salesforce is going to disable SSL 3.0 and enable TLS 1.0 which is the next heigher version of SSL 3.0.
TLS and SSL encrypt the segments of network connections at the Transport Layer end-to-end.
All SMTP connections start in plain text and can be switch to TLS
For outbound emails it is up to the receiving mail server to switch the conversation to TLS, you need to ensure the mail server for TLS.
