Hi @melshity,
By default, WordPress uses the PHP mail function to send out email notifications. However, this function doesn’t work as expected due to a number of reasons.
Most WordPress hosting companies restrict usage of this function to prevent abuse and spam.
Spam filters on popular email service providers check incoming emails to monitor if they are sent from authentic mail servers. Default WordPress emails fail this check and sometimes may not even make it to the spam folder.
SMTP (Simple Mail Transfer Protocol) is the industry standard for sending emails. Unlike the PHP mail function, SMTP uses proper authentication, which increases email deliverability.
You can further check this plugin and how to configure it from this WordPress video:
Additionally, you’ll need to allow outgoing ports 465 and 587. You can do it like so :
sudo iptables -A OUTPUT -p tcp --dport 465 -m conntrack --ctstate NEW,ESTABLISHED -j ACCEPT
sudo iptables -A INPUT -p tcp --sport 465 -m conntrack --ctstate ESTABLISHED -j ACCEPT
and
sudo iptables -A OUTPUT -p tcp --dport 587 -m conntrack --ctstate NEW,ESTABLISHED -j ACCEPT
sudo iptables -A INPUT -p tcp --sport 587 -m conntrack --ctstate ESTABLISHED -j ACCEPT

Hello there,
What I could suggest here is using an SMTP plugin for your WordPress site.
That way you will be able to specify an SMTP server with authentication which your emails would be going through. You could for example use Gmail’s SMTP settings. This would drastically increase the delivery rate of your emails as well compared to using plain PHP mail.
I’ve been using this plugin for a while now and it works very well: Easy WP SMTP
Hope that this helps! Regards, Alex
