So, the story is a little long. Any help would be very much appreciated!
I had a blog on CloudWays, and it was sending emails normally, when someone post comments, etc.
The blog gone offline, I cancelled my server. A few weeks later, I decided to put it online again. I've signed up for another Cloudways server, and put everything online.
Now, the blog is not sending emails anymore, whenever someone posts a comment. No emails warning me, the administrator, no emails from the plugin "subscribe to comments", etc. No emails in geral from the WordPress blog.
The technical support said me that WordPress sent emails through PHP, and this could be blocked. They asked me to install the SMTP addon. But, does this make sense?
Sorry, I didn't understand very well. And, well, how will I configure the SMTP addon inside my WordPress?
