Sending Mail

RAIL clusters provide their own SMTP service that you can use if your application needs to send email. This service can be used from within the cluster without providing authentication.

The address of the SMTP service is smtp.${rail_region}.${rail_env}.rail.uhdc.no. You connect to it using the standard port 25 on an unencrypted connection (without TLS).

• what happens with email that bounce?

• are there limits on how much mail you can send?
