I can send email, but can't receive any.

Hi,
I’m being able to send email from my site but unfortunately not receiving any email. I tried in many ways but was not able to solve the problem.

Is there anyone who can help me out with the issue?

Thank you.

I had the same problem

solution:
groupadd spamd
useradd -g spamd -s /bin/false -d /var/log/spamassassin spamd
chown spamd:spamd /var/log/spamassassin
systemctl enable spamassassin
systemctl start spamassassin

Look here : Install SpamAssassin and Stop Email Spam on CyberPanel! - CyberPanel

All the settings was the same as like as mentioned in the blog.
I just restarted postfix and i worked like an angel.

Thanks a lot man.

Thanks guys. This one worked fine. Just need to mention that these are root commands to remove the confusion of whether to access the root folders or not.

For a weird reason it happens once again without any reason.

Again i stopped to receive any mails.

My mail log are saying so,
