I will need a Shell script that is configured on CentOS 7/8;
Mailwizz / run with SSL
Postfix Mailserver / implement specification on the server works on port 587
DNS to set a domain / generate automatic "NS" to configure domain
rDNS reverse name server / detect rDNS, if no DNS does not proceed with the installation
DKIM / implement specification in the domain and email server
SPF / implement the specification in the domain and email server
DMARC / add policies to the server
IP Rotation (detect all IPS of the network card and rotate/change IP every 1 hour "to send email")
