whitelist for DNS check

Post by supportterabox »

Hi all,

i had a problem although i searched on internet a lot but no luck.
my os is Centos 7.
zimbra version is 8.7 open source.
i configured mail server like this.
checked reject_unknown_client_hostname
checked reject_unknown_reverse_client_hostname
checked reject_unknown_sender_domain
checked reject_unknown_helo_hostname

i want to receive email from server which does not configure reverse DNS but it still keeps this configure.
how can i do that ?
i have ever tried whitelist for this but no luck
anyone has any idea
i appreciate that
