SMTP Question(s)
zero12785 said 1 year ago:
Hello.
I am a web developer, and have had little experience working with non-shared hosting. Here’s the story: I have hosting here, that’s irrelevant. I have a web server here for a game, the website I have developed integrates with said game’s databases. I recently found that WAMP (my server software set of choice) does not offer SMTP. No biggy, I’ve installed an hMail server and i finally got that working. My issue is I figure since i own the domain, and the server, I should be able to legitimize my emails it sends out, for registration and the like. I looked into it and i think what i am missing is a DKIM key? So my question(s) is(are) this: What is a DKIM Key? How do i get one? Does it cost? If this is the wrong path to look into, what is the right one? summary: How do i go about making my game/server’s website emails be considered authentic by some/most providers?

I am not too familiar with a DKIM key. I did some research online and found the following link which goes into detail regarding what it is and does.
Unfortunately, I have little experience with configuring servers to send mail and am unsure if this is what is needed to improve authenticity of your emails. I know you can add an SPF record to your domain’s zone file to have SMTP server check to ensure only approved servers are sending email for your domain, however I am unaware of how much this impacts authenticity of the emails actually being sent. Hopefully, other forum members have more experience with this setup and can offer information to address your questions and concerns.

Yea, i read their site yesterday, but it was kind of confusing. Could you tell me or link me to a guide for how to go about trying your idea? And what its effect is if possible (teach a man to fish, etc). That way i understand what it does 
Any assistance is helpful. Thanks for the speedy reply also!

This article will show you how to add an SPF/PTR record to your domain’s zone file:
Managing DNS for Your Domain Name
An SPF record can be used to limit which servers can be used to send email using that domain.
