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).
I thought about self-hosting, but first of all I got a dynamic IP. Further I want a solution which has roughly 98% availability and 99,99% reliability, because this service tells me if everything burns/ goes awry. That’s not the service I’d like to “toy” with. And hosting any kind of mail service with 98% availability and 99,99% reliability, automatic DKIM roll-over etc. is a tough nut. Even VPS cost’s seem higher than just Amazon SES.
