We want to setup our SMTP server in Confluence to send email. If I setup with port 25 it works like a charm. But we need to configure it through SSL with 465 port.
If I setup the port 465 I receive this error:
And we cannot select TLS option because our server is working with SSL instead of TLS.
¿How can we proceed with this environment?
Thank you very much
SSL/TLS can be a bit confusing because the name changed even though they're doing the same things. TLS 1.0 would be SSL 3.1 if they'd kept the name instead of changing it.
Despite us saying "SSL certificate" or "SSL configuration", we generally mean TLS 1.0 or above because SSL2 and SSL3 are both proven to be very insecure now.
My advice is to select that TLS checkbox in the mail handler configuration in JIRA. Chances are that your mail server is actually set up with TLS 1.0 or better already. And if it's not, JIRA will try to use SSL2/SSL3 depending on what's configured on your mail server.
Bummer! If your SMTP server is accessible from the internet (i.e. you can send email outside your office without having to connect to VPN), you can try using the tool at https://www.checktls.com/perl/live/TestReceiver.pl - you can just enter some dummy email address on your domain like "test":
Look for the TLS column (highlighted above). If it's not OK, you'll need to work with your mail server administrator to get it enabled. This varies depending on what mail server you're using and is outside something we're able to help you with here.
If it does say OK, check with your network team to see if there are any firewall rules in the way between your JIRA server and your mail server over that port. It's also worth checking to make sure the mail server has a signed certificate from some place like Comodo, GeoTrust, or DigiCert. Self-signed certificates might cause a problem. If you're using Java 7, ther are also a few certificate providers like GoDaddy that require some extra configuration to be accepted by Java.
