What happens when there is a power or ISP outage?
Most email servers are set up to resend automatically for a while, potentially for a couple of days.

#12The hardware looks slick, but are my emails going to bounce when my not commercial comcast/spectrum/at&t/whoever has a maintenance outage? I'm not sure it's too useful to bring that out of the datacenter and into my house...
Most SMTP hosts will automatically retry a few times at spaced intervals if they can’t reach their destination host in first attempt.
Yea, they will retry for 48 hours before a message is marked as undeliverable.

#13How hackable is this I wonder? Would just be cool to have a machine this shape. Of course you could probably do the same with a raspberry pi and a 3D printer.

MTAs will retry delivery for up to a week. There are other options for more advanced usage though, e.g. one can configure multiple mail servers with different priorities, `the helm` having the highest priority and if it's down a MTA would try the next mail server which could be just a forwarder like mailgun.

They have a sort of FAQ on their shop page that provides info about this: https://thehelm.com/pages/shop
See under the question: What happens to my email if my power or Internet service goes out?

If your ISP doesn't let you run your own mail server, they're not an ISP.

Plus they tend to block the ports you need to run something like this.

It's not necesarily banned, but very often port 25 will be blocked. Additionally it's pretty likely your email will be marked as spam if it comes from a residential IP. They must have thought about this though, so maybe they have their own SMTP servers that emails go through.

Email has several retries. Something like 6hr, 1day, 2days... After that the sender receives a delivery error.
All that is managed by the SMTP servers and the numbers change, but normally just losing internet connection or power for some hours doesnt make emails dissapear. By design.

Hey there, I'm Giri Sreenivas, co-founder of Helm. Glad you like the hardware! Good question on email bounces. As Arubis mentioned, email has retry built in and most servers default to retrying for 48-72 hours.
