What exactly is happening to your outbound test messages? Is the recipient MTA accepting delivery but filtering? Are you seeing rejects from the MTA? If so what's the error? Try sending messages that are ordinary looking (not "Testing, testing...").

How long has the sender domain been registered?

> Email is one of the bastions of the decentralised Internet and we should hang on to it. This. I hope someone will eventually create an "E-mail server in a box" package for Ubuntu LTS, so that more people can run their own E-mail. I'm not saying it has to be super-easy for everyone, just that it should avoid unnecessary chore work (like configuring postfix to always use TLS, or plugging postgrey into postfix).

The "email server in a box" is called a Mac Mini with the Server package. It's such an easy-to-use email system. Been working great on a home static-IP address for me for a couple years now.

Maybe when (if?) Apple releases a new one. Right now the hardware on the Mac Mini is so pathetically underpowered for the price, and Apple has shown such blatant disdain for both the Mini and the Pro that it almost feels like they don't want customers for those product lines.

I suppose that's a trade-off against how reliable you consider your ISP and electricity supply, and the volume or importance of email you'd be likely to receive in such a period.

Bounce? No. The servers trying to send mail to your server will retry for up to, typically, four or five days, before they bounce the mail back to the sender. Mail was written to be resilient against network downtime.

That's why you soft bounce. It tells the sender that you can't receive the email _at this time_.

If you are having trouble with Google putting your emails into spam folders, email to yourself at Gmail. Then examine the original headers ("show original") and check the authentication header Google adds. It begins:

Authentication-Results: mx.google.com;

and details what it did and did not like about your message. For example, it let me know my mail server had suddenly started sending over IPv6 (actually, Google started accepting there and IPv6 had priority) and I only had SPF records for the IPv4 address. Google's authentication results are the friend of everyone with a personal mail server.

Yeah I'll have to disagree here. I beat my head against this horribly documented MTA just trying to get virtual users to work with a relay host. I gave up after three days of slitting my wrists trying to get it to work. It's horribly documented, getting help out of the obsd folks is like getting blood from a turnip, but if it works for you great! But I would never agree it's easier to configure or has better document…

I'm genuinely curious here since opensmtpd has been by far the easiest to configure MTA I've ever seen. What problem(s) did you have? Virtual users through a relay host is literally one simple line: accept for domain "example.com" virtual relay via relay.example.com I don't see how anyone could conclude that is more difficult than postfix.

And have you tried it? Because when I tried it it did not work as documented.

SPF, DKIM, DMARC could be dropped if you actually use aws ses to send your mails, you can actually forward the mails there. So it's pretty impossible that your messages will be in spam. The only thing you need to manage is incoming mail now and not being a open relay.

Unfortunately SES servers seem to be regularly blacklisted. A quick google confirms. I've been using SES for 3-4 months now and had a few hard bounces with specific mention to the IP being banned.

The last spam that got through GMail's filter was from amazonses.com. It wasn't clear how to report it back to Amazon.

It's absolutely possible to run an email server in 2016 and I encourage anyone capable to do so! Email is one of the bastions of the decentralised Internet and we should hang on to it. Every day more and more people are moving to Gmail/Hotmail/Outlook and while I do understand the reasons, it also puts more and more power into the hands of these providers and the little guy (us) gets more screwed (like marked as junk…

Any open source mail servers taht set all this up? Last I checked in 2011 there weren't any.
