Problem

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

Diagnosis

Environment

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

Cause

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

Resolution

Disable the email checking section of the antivirus
