Hi Nicola,
Unfortunately, this is a problem at the server level. The plugin sends email using a core WordPress function, in exactly the same way other WordPress emails are sent. It seems that your server has a low spam reputation. It’s rather shameful that your web host did not take responsibility for this.
If you want to send via SMTP as they recommend, you could look into the WP Mail SMTP plugin. You may need some help from your web host to setup the appropriate SMTP values.
Hi,
this is the server answer:
Dear Customer , actually the web server hosting the site is to be blacklisted on some RBL However the authors of the plugin not knowing our infrastructure can not know that sending is done by another server , with different IP and not present in any RBL .
We indeed tested sending to a free tool to test email through a script that we created on his FTP root mail.php called , and the result is 7 points out of 10, below the result :

So we insist that the problems are related to the application and not on our infrastructure .
To send mail via SMTP must use a special plugin , but it is not within our competence to recommend search for it online or contact a webmaster .
To configure sending still use port 25 or 587 , password authentication without SSL / STARTTLS .
PLEASE WHAT CAN I DO???
Hi Nicola,
To be honest, you should change your web host. If their servers are blacklisted and they’re not taking responsibility for getting you to a better server, that’s a big red flag.
That said, if you stay on your server, you should probably just send mail using SMTP as they recommend. The plugin I linked to in my last post will help you do that.
