There was a time that I was able to configure e-mail servers for JIRA but I don't know how it is missing now!
I searched but the only suggestion I found was about JIRA System Administrators role and global permissions which is not my case.
I can only see Mail Queue and Send Mail links but where is the Outgoing Mail link?
By the way, my JIRA version is a 6.3.14 standalone installations. Thanks in advance for your helps.
