> The _real_ problem is reliably getting your 100% legit mail into your consenting recipients' inboxes It's amazing that having someone in your address book isn't enough in many cases. Like, why?

I moved a Gsuite client to Zoho because once or twice a week, an email from one person at the custom domain to another person in the same custom domain (company) would have their direct email get put into spam in Gmail. You would really think that Google would whitelist emails within the same custom domain which is paying for Gsuite service. Maybe that has changed, but it was definitely a problem 5 years ago. And we'…

Google's own emails about expense reimbursements were systematically flagged as SPAM on gmail and they knew it.

They still didn't care at all!

I've used https://mailu.io . It works well, but your biggest problem is going to be getting over the spam filter hurdles of the email giants of the world. Even if everything is properly configured (including dkim / spf / whatever else they've added) your messages will get plopped in the spam folder.

My experience is, that the „quality“ of the mail server‘s IP really matters. The worst experience I got was with digital ocean. A lot of providers just don’t accept email from their IP ranges. Some of them just completely block all DO IPs on router level, and refuse unblocking. For my current server I had to switch IPs a few times, until I got one that was not blocked by any of the major providers. Unblocking a once…

This will hopefully help recover DigitalOcean's IP space reputation for good actors: https://www.digitalocean.com/blog/smtp-restricted-by-default but it's going to take awhile.

THIS. Spam is a solved problem, thanks to SPF and DKIM. But despite doing all the right things, Microsoft and Google continuously block and rate-limit delivery. Case in point: we deliver 20,000 booking confirmation emails every day, all requested by users and not spam. We have perfect Postmaster Tools metrics: absolutely zero reported spam, 100% IP reputation, high domain reputation, zero feedback loop spam, 100% enc…

Really hoping ENS can step in here and fill this gap. There's a lot of work being done on social and messaging infrastructure. Using that as an email and chat handle and social handle would be huge for maintaining open messaging. Unfortunately this relies on adoption and people living past their bias and admitting there's use cases.

What is ENS?

I've been doing it for well over 20 years now. Ingress - out of the box rspamd is pretty decent and it is rather configurable. Egress - DNS (A,AAAA, PTR), (E)HELO, SPF, DKIM, DMARC. "IP Reputation". There are absolutely no shortcuts and yet most of the problems I diagnose regarding email delivery will find a missing PTR record or a miss-configured (or non configured) HELO. You cannot be lazy when it comes to email. S…

> Egress - DNS (A,AAAA, PTR), (E)HELO, SPF, DKIM, DMARC. "IP Reputation". Any insight into why this is a giant ball of complexity? I’ve had to setup spf, dkim, dmarc a couple times now and man… design by committee?

There is no design committee, they just keep adding stuff over and tell us is definitely the one that will fix security/phising/privacy/spam issues SMTP suffers.

I think it’s a miracle E-mail still works at all this far into web whatever-point-oh we’re in.

I'd like to try it, but the landing page writing doesn't inspire confidence that this is a polished product.

If the developers are reading this comment, I might be able to help tighten and smooth that out. I have 99.9999% English fluency and write at the highest calibre.

How many servers do you have? Just curious if the rate limit is per IP address?

We have a Microsoft email subscription (all our mail is hosted with them), and their smtp server rate limits how much mail we send to our customers. We can’t even send 30 emails at once. We had to implement retry logic with back off.

Why not just use Sendgrid or similar for SMTP emails to customers, get a dedicated IP with them and have way less concern.

I always prefer to isolate those things from the main corporate email and reputation anyway.

You don't want your main domain getting hacked and affecting customer emails or vice versa.

I feel like this solution is optimizing the wrong problem. The bulk of work with managing a mail server (these days) isn't software setup and admin. On the receiving side, it's all the work dealing with abuse and attacks. On the sending side -- and this is the tough one -- it's getting sites to accept your email.

I'm a former sysadmin and as such can remember the days when it was almost considered fun (at least by nerds) to run your own mail server.

Those days are long gone, and the reason why is that monopolistic companies hate open protocols like email and want to 'monetize' everything they can.

Counter point... Make email hosting as easy and abuse free that many more people can host their servers( for themselves or for community) breaking the big tech monopoly.
