So the site I am trouble shooting is http://www.rentlucky.com
The site has been sending out emails just fine up until March 26. We are using Contact forms 7 and WP-Mail-SMTP. We were using them before too. I have tried to send emails through smtp but that just errors out. So it has to be PHP mail() function.
It claims to be sending mail and it even comes out at Bool true when I do the test email.
I also created a new user and told it to email me my pw. I have not received that email at all. So wordpress itself is not sending the email. I need suggestions.
