問題

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

診断

環境

• An antivirus is installed and enabled in the server hosting JIRA

原因

The antivirus is scanning the email connections, in particular the SSL connections. This causes problems as the majority of mail servers uses HTTPS.

ソリューション

Disable the email checking section of the antivirus
