Hi there,

what SMTP relay’s / services do you use or can recommend for sending monitoring alerts.

I’m running a few services, but mostly all my custom scripts, and tasks are configured to sent an e-mail if something goes “off-script”. Before I used my gmail account - but I’m in the middle of migrating away, and my requirements have evolved.

I’ve searched but I haven’t found anything good. Services like Mailgun, Mailtrap etc. are nice - but their bundle’s are a bit much for my taste.

The service/ relay should meet the following requirements.

  • bring your own domain (use your own domain/ or sub-domains as sender address)
  • must have DKIM (anything else is not a serious service!)
  • support SMTP via TLS
  • support multiple SMTP clients, with each different credentials/ secrets
  • Allow custom header/ envelope changes

At the moment I’m looking at Amazon SES, because I don’t expect a lot of messages (I had 3 alerts in the last 1,5 yrs).

    Have you thought of self-hosting mailcow? https://github.com/mailcow/mailcow-dockerized

    It’s very easy to set up and fairly straightforward to maintain, if you have a static IP and it’s not impossible to get a PTR record then I highly recommend it. Yes you’re self hosting your own mail server but mailcow vastly simplifies this.

    Alternatively plonking it on the right VPS can also work.
