 This app will loop through all the mail in an IMAP account and geo route all messages.  You can use the live feed on your mailhops.com account to monitor your incoming messages.  Leave it running and it will route incoming messages.
 
+You can also add a [custom Slack integration](https://mailhops.slack.com/apps/build/custom-integration) to post messages to Slack.  Use the subjectFilter or fromAddress in [the config](config.sample) to limit the messages posted to Slack.
