JIRA shows SSL error when setting up emails
When trying to set up the email in JIRA (Mail Handlers or Outgoing Mail Server), an SSL error occurs when trying to send/receive email, despite JIRA not configured to use SSL.
Example SSL errors are :
com.sun.mail.smtp.SMTPSendFailedException: 530 5.7.0 Must issue a STARTTLS command first. xt9sm7519059pbc.14 - gsmtp
sun.security.provider.certpath.SunCertPathBuilderException: unable to find valid certification path to requested target
- An antivirus is installed and enabled in the server hosting JIRA
The antivirus is scanning the email connections, in particular the SSL connections. This causes problems as the majority of mail servers uses HTTPS.
Disable the email checking section of the antivirus
