I am running a few websites which have a simple feedback forms which POST to a simple PHP script that sends me an email.

By filtering for a few keywords, you can get of 99% of the form spam.

Deliverability has never been an issue for me since (of course) I run my own mail server. But I doubt it's a serious issue when you take the little time it takes to set up DKIM etc.

I wouldn't make it more complicated than it has to be :-)

I have a form on my website to leave a message on the /guestbook

I added the simplest and most basic of captchas and so far I got 0 spam. It’s been online for months at this point.

Sometimes a stupidly basic solution works incredibly well.

My Go script is pretty simple too, I'm more worried about the stuff around it really. How do you host your PHP script by the way?

Interesting, didn't think about it. You do this in the UI logic before the form is submitted? What keywords do you use?

Fair enough, I assumed this would be an issue so I never explored the possibility of hosting my own mail server.

I would add a simple db to save the form submissions - this way there would be no risk of losing data in case the email did not arrive

I agree, I even went the other way and removed the email notification and just kept an embedded SQLite database. I figured that's more reliable than hoping the emails always end up in my inbox.

True. No Service needed. Just a cheap php webhosting, a simple Form and a php script
