The goal of that Ansible role is to configure a dedicated node as a mail relay/gateway that would perform antivirus/antispam checks, and would log everything in a DB. Then it would forward all the mails to the real mail server. The tools used/configured/deployed by this role are :
- postfix
- mailscanner
- mailwatch
- clamav/clamd
- spamassassin
- selinux custom policies
This role has been tested only on CentOS 7 (so should work on RHEL 7 too)
