When I enable SMTP I'm getting a 500 error

When I enable SMTP I'm getting a 500 error(www.mysite.com is currently unable to handle this request.) on all my forms, I have about 5 websites on my server that's giving the same error, what is strange though is that the form submission is successful I can see it in the forms entries , if I disable SMTP the form works, but I'm still not getting any submission notification

Who is your hosting provider and do they allow SMTP?

I have two domains with GoDaddy at the moment - one is hosted with their deluxe whatever hosting and the other is their deluxe whatever hosting with cPanel. The cPanel hosting allows SMTP but the other does not so be sure to check and see if it's even possible.

Was searching for this same error as it is the one that the showcase server could not recognize the command due to a syntax error. While searching on SERP it also tells that some random requested commands failed because user's mailbox was unavailable. Well, as I'm using a platform: cloudways.com/en/php-hosting.php ... so my obstacles of such errors are now reduced by their own customer support
