Hey @somlogabor,
Sorry to hear about the challenge you’re facing with the spam bot emails.
When Easy WP SMTP is set up, it significantly improves email delivery. When the delivery problem is fixed, it fixes it for all emails. This means both legitimate emails and spam will be able to make it through, as our plugin doesn’t determine what email is legitimate and what isn’t. It passes all emails over to the mailer service.
What you’ll want to do is stop spam at the source, which is the forms on your site. Stopping spam before it can be submitted will stop WordPress and Easy WP SMTP from processing it. This not only stops spam from landing in your email, but it also helps prevent your hosting account from running unnecessary processes, which can affect your resource usage.
Check with the developer of your form software. Often, they will have specific recommendations on how to stop spam from being submitted. For instance, WPForms has several built-in methods of mitigating spam: https://wpforms.com/docs/how-to-prevent-spam-in-wpforms/
I hope this helps! If you have any questions, feel free to let me know
