I have been working with Cloudways support with this with not much success. According to them, the class-phpmailer.php file on many of the sites I host are sending a lot of mails, qq.com crap.
This stops emails from forms being sent which effect my clients.
It is effectively up to me to fix but i have no idea what im doing, looking for, where to start. I am at the point where I probably need to look at (god help me) fiverr or something to find someone to work out what is going on.
Cloudways inform they do not support application level issues, nad have just been told to find a developer to fix. Support have been great up until this issue.
Will probably have to look for a full support host after this.
Sorry, just upset and desperate.
