Enabling Ports

[Bruce Embrey <embrey hood edu>]

Hi,

I am running RHLinux7.2 and during the installation I selected High 
Security on the firewall and selected HTTP and SSH. I now want to open port 
25 for sendmail. I ran nmap and my port 22 and 80 were open but not 25. I 
checked the /etc/services and it appears port 25 is enabled for tcp and 
udp. I checked my ipchains and it shows the policy for SMTP is identical to 
HTTP and SSH policies.

I have not yet configured sendmail and was wondering if after configuring 
it and starting the daemon will port 25 be open or where do I need to look 
to open this port?
