SMTP not working #106

Closed jarischaefer closed 4 years ago

jarischaefer commented 5 years ago

I am having this same issue getting SMTP to work with docker librenms. The UI gives "Test to mail failed SMTP connect() failed. https://github.com/PHPMailer/PHPMailer/wiki/Troubleshooting" when I test transport. Log file mail.log is not written to and neither are any of the files in ./logs/ with mail failure details.

I have been working on this for several days now. Alerting in previous install without docker worked fine. Any help greatly appreciated.

@hmajidy2001 how are you accessing the SMTP server? Is it an external connection (e.g. mail.example.com), a linked container (e.g. --link mailserver:mail-backend) or perhaps a docker network?

The first thing you could try is pinging the mail server's IP address (if your firewall permits) from inside the container (e.g. docker run --rm jarischaefer/docker-librenms ping example.com).
