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).

    Most distro provide either EXIM or Postfix installed by default, and configured to send outbound emails from localhost. All you need to do is start the service, change /etc/aliases to add root: <your.email@dre.ss> and run newaliases.

    You don’t need MX records for that. MX is only needed to receive emails on a domain. Worst case is your monitoring emails will end up in spam (because there’s no SPF configured for your machine), but your spam filter will eventually accept them as you move them from the spam folder to inbox.

    Pretty KISS in my opinion. More than changing all your apps to use an external relay, setup accounts, yada yada…
