Allow IMAP Clients to Access the Server
An XCCDF Group
Description
The default iptables configuration does not allow inbound access to any services.
This modification will allow remote hosts to initiate connections to the IMAP daemon,
while keeping all other ports on the server in their default protected state.
To configure iptables to allow port 143 traffic, one must edit
/etc/sysconfig/iptables and
/etc/sysconfig/ip6tables (if IPv6 is in use).
Add the following line, ensuring that it appears before the final LOG and DROP lines for the INPUT chain:
-A INPUT -m state --state NEW -p tcp --dport 143 -j ACCEPT
