Not receiving emails

I have my MX records as follows:

I am not getting emails and system status does not report any new issues. please note that I’m not using MiaB DNS.

10	mail.camva.ir	162.13.85.94	5 min	
20	30335462.in1.mandrillapp.com	54.71.32.218	5 min	
30	30335462.in2.mandrillapp.com	54.71.32.218	5 min

How can I figure out what’s wrong?

Remove the Mandrill records. Wait a while for DNS to propagate. Then look at /var/log/mail.log to see if mail is incoming.

it does get emails. but they mostly are going to spam folder.

I used my personal gmail account for the test
