This plugin delivers to another SMTP server, bridging the authentication details and post data from the initial connection.

This plugin is meant to be used with the plugin auth/auth_bridge.

It is different than queue/smtp_proxy or queue/smpt_forward because it doesn't use the AUTH details from a configuration file. This plugins simply post the data from the original connection to the remote SMTP server using the original AUTH details.


Configuration is stored in config/smtp_bridge.ini and uses the INI style formatting.

The configuration of this plugin is simple:

  • host: the host where you will be authenticating and posting,

for example smtp.host.tld. This is the only setting required.

If needed you can also set

  • port: default to empty and Haraka will use 25.
  • auth_type: default to empty and Haraka will try to pick an appropriate method.
  • priority: default to 10.
