Hi, I'm sad to hear you are having issue with spam emails.
Have you tried spamassasin and advanced spam option into centos panel?

I like this panel but i cannot currently use due to some email SSL issue. I will try to see if there is someone of the Centos Panel Team that can reply.

If you are unable (as me with a current another panel) to manage spam you can try https://mxguarddog.com/ service. I'm using that as i started to have a big spam issue.

HI

Sorry to hear that u have spam mail issue try the below code in Postfix configuration
/etc/postfix/main.cnf
add some rbls to reject spam emails also check for any malicious code inserted in your website

Code Select Expand

smtpd_client_restrictions = reject_unknown_client
smtpd_helo_restrictions =
smtpd_sender_restrictions = reject_unknown_sender_domain
smtpd_recipient_restrictions = permit_sasl_authenticated, permit_mynetworks, check_client_access hash:/etc/postfix/sender_whitelist, check_client_access hash:/etc/postfix/sender_blacklist, reject_unauth_destination, reject_non_fqdn_sender,reject_unknown_sender_domain,check_sender_access hash:/etc/postfix/access, reject_non_fqdn_recipient, reject_unknown_recipient_domain, reject_rbl_client zen.spamhaus.org, reject_rbl_client bl.spamcop.net, reject_rbl_client dnsbl.sorbs.net, reject_rbl_client cbl.abuseat.org, reject_rbl_client b.barracudacentral.org, reject_rbl_client dnsbl-1.uceprotect.net, reject_rbl_client noptr.spamrats.com, reject_rbl_client dyna.spamrats.com, reject_rbl_client spam.spamrats.com

smtpd_helo_required = yes
unknown_local_recipient_reject_code = 550
disable_vrfy_command = yes
smtpd_data_restrictions = reject_unauth_pipelining

then restart postfix and check the log mails from unknown will be rejected also dont forget to check the options in mailserver manager to check the options
AntiSpam/AntiVirus (recommended): ClamAV, Amavis & Spamassassin, Requires 1Gb+ RAM
rDNS Check (recommended):    Drop all emails if no rDNS/PTR
Install DKIM & SPF (recommended):Installs DKIM & SPF, enables DKIM for New Accounts and Domains
then rebuild mail server
This will block almost 95% spam emails
