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).

    As you please ;)

    Be aware that I’ve been doing that for all my servers for the past 5 years and it works like a charm. I run OpenBSD, and only need to rcctl start smtpd to start sending outbound emails.

    They’re all sent from “root@host.domain.tld”, which have neither SPF nor DMARK records, and end up in my inbox no problem (I use spamassassin as my spam filter). They won’t end up on Blocklist as the volume is just waaayyyyyyy too low anyway.
