Looking for a free SMTP Relay Server that is REALLY free
I'm looking for a truly free SMTP Server. Years ago we used QK SMTP Server, which worked fine, but it doesn't look like they updated it since 2007. I've been searching online for a free smtp server, but articles will say things "10 best free SMTP servers" and they are not truly free. I don't want free for 30 days or there to be a daily or monthly limit. Can someone suggest a good FREE smtp server?

Please tell us the amount of Mails you must process on average: hundreds, thousands, ten of thousands, ... per day.
I have some devices sending a a fee emails every month using https://www.smtp2go.com/.. If you have a lot of volume, I doubt something will be free.

No such thing as free.
Options...
1) If you run your own MTA (QK or any other), you'll also have to setup + manage your own infrastructure.
https://www.experts-exchange.com/questions/29194498/how-to-configure-smtp-in-wamp-server.html provides a bare bones checklist.
In this case the SMTP code is free (OpenSMTPD, Postfix, EXIM, qpsmtpd, whatever) + the setup/maintenance cost may require many hours/day, especially to managed your DMARC reports + Feedback Loop reports to fix delivery problems.
2) Or you'll use a relay service like https://MailGun.org where cost is per message sending fee.
3) For high volume mail you'll likely use #1.
For low volume mail... say <100K messages/month, you'll likely choose option #2.
If what you're selling has a high price point, you'll likely also choose #1, so you're in complete control of your delivery/inboxing.

eFa is a filtering appliance (removes spam), not an SMTP server. If I install the SMTP server in Windows Server 2019, it installs IIS 6, which is a very old version (IIS is now at version 10). Microsoft no longer supplies SMTP in IIS after version 6 and it would be a security risk to install IIS 6.

Run postfix under a linux VM.

Eric, is smtp2go an on-prem solution or cloud? This is only going to be for 5 devices so the email volume will be extremely LOW. The devices only send an email if an alert is thrown on the device. Sometimes weeks will go by without an email going out.

If this is internal, then using smtp on the server could do the trick.
An alternative would be using your smtp credentials for Gmail.
But the best option is going to be paid solution like sendgrid and the like. Sendgrid does have a free version and after checking it, they change the policy. I think it used to be a fixed amount of free emails until you have to convert, now it is 100 per day max forever. https://sendgrid.com/free/ This is the option I would go with especially if email is going external.

As @kevinhsieh mentioned.
1) Running Linux provides a huge number of options.
2) And best to run Linux in a VM, if you're running Windows at the machine level.
3) Alternatively, you can lease OVH/SoYouStart/KimSufi servers starting at $5 USD/month to have a dedicated, physical server.
