I have a need for an internal SMTP relay inside a kubernetes cluster. What is everyone using for docker/kubernetes SMTP relays these days?

Goal is to have all internal services route emails through this relay and it in turn sends the emails out via SendGrid, should be a fairly easy task, just not something I've done for a few years.

I think I'm going to end up using docker-mailserver for this.

That seems really resource heavy. 4 Gb of RAM for an SMTP relay?

Other than that it looks pretty great.
