Incoming Emails to default Service Desk email encrypted?

[Nelson Ra]

My organization is setting up a service desk project whereby emails sent to a distribution list are forwarded to the default service desk email account to create tickets. The question has come up whether emails forwarded to the default account would be encrypted.

By default, if the mail is coming from SSL it should be secured enough.

POP / IMAP over SSL
You can encrypt email communications between JIRA and your mail server via SSL, provided your mail server supports SSL. 

Firstly, you will need to import the mail server certificate into a Java keystore. The process is described on the Connecting to SSL Services page.

 Important Note: Without importing the certificate, JIRA will not be able to communicate with your mail server.
