and yet we assume they are wealthy enough to own a mobile phone and/or computer/tablet to access that email.

Contrary to popular belief, most homeless people have cellphones.

well then however they are affording a mobile phone and the monthly service, they can probably figure out how to pay $5/month for email if they don't want to use one of the free options.

I run a small transactional email provider ( https://mailpace.com ), our IPs are very rarely added to blocklists- but we are very strict on what we allow through our service, and surprisingly we’ve had no long term delivery issues with any of the big providers. So thanks to the federated/decentralized design of email, is totally possible to be part of the network without any special privileges. We are sending million…

Right. When I changed my vps to another hoster, I totally forgot how much trouble it was to get a good reputation in the beginning. But it was really not that much work again. Just unfortunate, because one big Mail provider just discarded instead of rejecting my mails. After this was settled, everything works quite nice again. Important to me is keeping spf, dkim, dmarc and now also mts up to date. See mail-checker.c…

Do you mean a different domain? mail-checker.com Looks like a parked spam domain.

Maybe ask yourself why some users end up blocking you altogether. Surely you didn't start sending them newsletters or the like without being completely certain that they wanted to receive them, and you provide a simple, prominent and reliable way to unsubscribe if/when they change their mind, right?

There's a block-by-default setup for new email servers. You have to go through the reputation-building process which is not at all clear nor is it always guaranteed to work. Yes, it "works" for most people, but it also has the effect of entrenching the incumbent large email providers and preventing more independent providers from cropping up. The current method is very lazy and collectively punishes a lot of innocent…

Exactly.

It destroys competition.

> I don’t have control over other Linode customers, guys! You do have control over being a Linode customer though. If Linode isn't doing enough to prevent abuse, they deserve to be blocked.

Asking infrastructure providers to police email content is a very invasive thing to want. I don't think I agree with that. Realistically, what can they do here? Make servers unaffordable to discourage abuse? Give most servers "Internet*" access where some ports are missing?

But that's how the world works right now: every provider has acceptable use policy, and not just for emails. Not necessarily because they care, but because they are beholden to an AUP, from their upstream or peers. Which makes it viral: if they won't hold AUP, they'd get cut off, and there's very little use in an internet service provider without connectivity.

The main benefit of Gmail and other big providers is the anti-spam, anti-scam, "Google knows best" approach works really well. When I last helped manage a mail server for a small business (late 2000's) SPAM was an absolute mess. You can really see why Azure etc has consumed on-premise Exchange. The massive downside is they are the deciders of who gets through their gates, and if you're on their shitlist, goodluck.

On the other hand, if the main economic mechanisms that help the major players did not exist, we might not have so much spam in the first place.

Tell me you weren't running an email server 20 years ago without telling me you weren't running an email server 20 years ago.

I love https://www.mail-tester.com/

One time, mail-tester.com found that my paid personal email hoster had moved my SMTP server to a new IP address without updating the anti-spam sender mechanisms. (You had one job, people.) When email is how you keep in touch with a lot of friends, and occasionally make new consulting contacts, that's relatively costly.

I had this problem for years. I would get the block lifted and it would return in short order. I surmise it’s because my mail server runs on a VPS and other users on my subnet are not well behaved (actually I know this for a fact). I solved the problem by paying for a next hop SMTPS server as an upstream smarthost for non-local mails. That means my mails come from a subnet that fronts TONS of other servers/domains. T…

I do the same thing, also with mailgun. It's generally much easier to deal with, especially if you have a fairly low volume of outgoing emails.

Mailgun has been very good to me, highly recommended.

I work on Microsoft's anti-spam team, AMA!

Similar question as my sibling comments. I have rented a server with a static IP address for over ten years now. Nobody else has used this IP during this time. Yet, every few months I have to beg Microsoft to unblock the IP. In the beginning I could do this on my own, but something changed a few years ago and now I have to beg my ISP (netcup) instead to contact Microsoft on behalf of me to temporarily whitelist the domain. Then wait another 2-3 months and do the same dance again.

Why? Why can Microsoft not learn that an IP has been healthy and spam-free for 10+ years and only bother me when there is actual spam is being sent?

Outlook/Hotmail blocks DigitalOcean. After half a dozens attempts over the years to delist my IP, and following all the best practices (dedicated fixed IP, SPF, DKIM, DMARC, FCrDNS, zero spam, TLS, etc.) I gave up. Eventually, most people realize that their Outlook/Hotmail email service is defective because they're not receiving emails, and they migrate to another email service.

This probably isn’t directly helpful or relevant advice, but I don’t see a good reason to spend double on DigitalOcean droplets compared to what you get with Hetzner Cloud.

* Stability: I've had zero issues in the last decade

* Latency: Hetzner's ping latency is more than double for me

* Switching costs: migrating hosting providers can be time consuming

That said, I agree that DigitalOcean isn't good value for money anymore.
