JIRA fails to send an email message stating:


The server's hostname is not set. JIRA is sending the server's IP address instead.


Resolutions include:

  1. Refer to your system's documentation to set the hostname correctly.
  2. Alternatively, add an entry in /etc/hosts.
  3. If this doesn't work, pass the hostname to JIRA specifically.

See Problems Sending Email from JIRA - EHLO requires domain address for details.

  1. if you add a hostname to /etc/hosts, you have to restart jira/confluence
