This looks really interesting, but I'm disappointed that you apparently _need_ a subscription to their DDNS-like service.

In a lot of cases, users may be paying for a static IP from their ISPs (or even have one for free, by default), or they may be running their own DDNS via a cloud instance already. This does nothing but add a $100/year fee for something that is exceptionally non-reusable and narrowly-scoped.

Don't most ISPs ban residential accounts from running something like this? Comcast terms: > use or run dedicated, stand-alone equipment or servers from the Premises that provide network content or any other services to anyone outside of your Premises local area network (“Premises LAN”), also commonly referred to as public services or servers. Examples of prohibited equipment and servers include, but are not limited t…

Even if you could send it, someone has to receive that email on the other end and the residential ips are usually blacklisted.

$99/year? They are targeting an extremely small market. I can get Fastmail for a fraction of that amount, and I don't see much of an advantage with this - and I'm one of the few willing to pay for something I get elsewhere for free.

The 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...

SMTP was designed around the assumption that nodes could go down or network partitions could happen.

If you are unreachable, the mail server that is trying to contact you should try again later.

How many times, at what interval and for how long retries happen vary.

Most servers will notify the sender saying that “message delivery failed permanently” if the receiver is unreachable for such a long period of time that the sender server gives up.

So between the resilience to temporary unreachability and the fact that the sender should be notified if delivery times out, I would say that the chance that anything important is lost is very slim.

The bigger problem is the fact that home ISPs often block outbound SMTP, as well as the fact that their IP blocks are often regarded as low trust by others, meaning that you will certainly run into problems sending mail every now and then. I did not yet read the OP link, but am going to, so I don’t know if they offer proxying/forwarding of outbound SMTP.

I feel like I'm the target market for this as I pay for Fastmail ..

1 - how many domains can I use? I currently use ~6 with my Fastmail account 2 - can I have multiple users? I recognize that fastmail doesn't let me but at this price point I would want it. It looks like you support that but I'm unsure. 3 - How do you convince my ISP to let me receive traffic on the ports required to run a mail server? (most firewall them on residential accounts) 4 - If I were this committed to my email, why wouldn't I just set it up for free myself? This is actually my biggest question in regards to the product/target market. Are there that many people out there that both care about how email works to this degree and aren't willing to host their own?

The website is heavy on theatrics and bold statements but I feel actually kind of lacking in terms of the meat. There's more than a few parts made it difficult for me to get any information at all (the automatic slide show on the Product page, the 'see the inside' slideshow on the tech page). If I had to guess I'd say this site wasn't tested against Firefox (doesn't seem that any are anymore due to its low market sharE).

My suggestion is to run an email server inside your home that connects to a single server on the internet (like a VPS) that routes your mail for you. It's a bit more complex to setup but much more secure and reliable and almost certainly won't violate ISP rules as long as you keep it secure.

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

Each Helm gets its own gateway server with static IP address that the Helm establishes a VPN connection with. Port 25 is open on the gateway and the packets are forwarded to the Helm. This is how we work around residential ISPs blocking port 25.

Holy crap, US ISPs are completely absurd. This definitely isn't a thing (or at least not enforced in any way) in Canada; most of my friends run on-prem web services out of their basements or closets.

In the US it's standard that residential accounts don't get to do that, but business accounts (which are usually double the price for the same speed but come with better/quicker support, particularly when physical lines are down, and an open connection) are allowed to run on-prem. And usually with a residential account you don't get a static IP as an option, but if you're lucky you can pay extra for one.
