This image allows linked containers to send outgoing email. You can configure it to send email directly to recipients, or to act as a smart host that relays mail to an intermediate server (eg, GMail, SendGrid). The default installation is the smart host version, for additional parameters to use as a smart host see the project link. https://hub.docker.com/r/bytemark/smtp/

Health score?A 0-100 score computed nightly from four factors: maintained (40%: recent commits and steady activity), popular (25%: GitHub stars, log scale), easy to install (20%: platforms, install notes, setup guides, Docker image) and light to run (15%: minimum RAM, ARM support). When the source code has been checked, a fifth factor, security check (20%: automated scan for committed secrets, unsafe desktop-app settings, known-vulnerable dependencies and project hygiene; any serious finding caps it at 20), is added. Factors without data are left out and the rest are rescaled.

Common questions

What hostname and port should linked containers use to send outgoing email?

Linked containers can connect to the SMTP container using hostname mail and port 25.

Can bytemark/smtp relay mail to an intermediate provider?

Yes. It can act as a smart host and relay mail to an intermediate server such as GMail or SendGrid.

Is bytemark SMTP available as an Unraid template?

An Unraid template repository support thread includes a bytemark SMTP container image.

If host-level telnet to an outgoing SMTP server works but container mail fails, what may be causing it?

A Docker networking issue may be the cause. In one report, the same setup worked on another host without the Docker network, so inspect the Docker network configuration.
