診断
- SMTP が適切なホストで実行されていることを確認します。不明な場合はシステム管理者にお問い合わせください。
- See if you can send mail with an application other than Confluence.
- Check the physical connection from the Confluence box to the SMTP host with the following:
Windows
Linux
- If you're unable to connect to the SMTP host from the JIRA host, it may indicate a problem with the network. Please check this with your hosting provider or System Administrator.
原因
The Mail Sever is not available/reachable.
ソリューション 1
Re-create the SMTP server settings in Confluence Admin > Mail Server.
Resolution 2
If the above does not work, move the 'activation' and 'mail' jar files from /confluence/WEB-INF/lib
to <Confluence Standalone install>/lib
, restart Confluence and see if the problem persists.
