Why is FormIt only working intermittently?

This has been driving me crazy. I have at least two websites (both 2.4.2-pl) that are being affected. I'll submit a form, see my success message, FormIt is saving the submission in MODX, there's nothing in the error log, but no email I use receives anything (5% of the time it miraculously works for some reason). Some of the tests seem to take days to arrive. I opened my email this morning and found a few tests I sent on Friday. Here is my call for a very basic form:

Is the mail being forwarded through another server? I do this with one email address forwarded through Bluehost and it often takes a day or so to get through.

If not, maybe it's your own server. I think some servers sit on the mail until a certain amount piles up before sending it.

The fact that you get any email suggests that FormIt is set up correctly, so it's more likely a problem with the server's email system.

I've found that if I set MODX up to use SMTP through Gmail, the mail generally goes out quickly and reliably.

so it's more likely a problem with the server's email system.

That's what I figured. I manage a lot of MODX sites with the same host and no others are having issues. They said there was nothing wrong with the server's email, but who knows. I tried the SMTP thing with Gmail and it's working perfectly now, thanks for that suggestion. Still very strange as i've never had to resort to it before.

I'm glad you got it working. Messing with email is absolutely my least favorite thing to work on.

I'm working on integrating the Mailgun service into the Notify snippet. I just sent 4 emails to different addresses. The Mailgun logs show all four as delivered and none bounced, but only one got through.
