I have successfully set up email from JIRA using (for example):
Protocol: SECURE SMTP
Host name: mail.<mycompany>.com.au
SMTP Port: 465
Timeout: 10000
TLS: No
Username: <myname>@<mycompany>.com.au
However, using the same details for Confluence (except Protocol because the option isn't offered), I am getting a timeout. Any suggestions?
