Port 25 not open

This is certainly only a sendmail issue as MailScanner does not listen to
any ports. MailScanner only retrieves files from /var/spool/mqueue.in, scans
them and puts them into /var/spool/mqueue. You must change the MTA line
instead of commenting it out to carry the IP assigned to the ethernet
interface. This is how I installed sendmail

Subject: Port 25 not open

We're installing a new server to use in production. I wrote a short list
of steps to install it the exact same way my test servers were setup.
Everything went fine, except port 25 is not open. (it's open on the
firewall settings, just doesn't show up in a port scan and of course we
can't send any mail to it).

MailScanner is definitely running. If I do "service MailScanner reload"
it reloads fine, yet port 25 is still not open. Anyone have any ideas?
The steps we used for installing everything is below. No, I don't know
if sendmail was working before doing the install, so it could be a
sendmail problem. If you think it is, I'll take other avenues to fix the
problem. Any suggestion are appreciated.


Here are the steps we took to install everything:
-Fresh install of Redhat 7.3
-Make sure port 25 is open with ipchains -L
-Edit the /etc/mail/sendmail.mc file and comment the following lines:
        dnl DAEMON_OPTIONS(`Port=smtp,Addr=, Name=MTA')
        dnl FEATURE(`accept_unresolvable_domains')dnl
-Recreate the sendmail.cf file by doing the following at the command
prompt: m4 /etc/mail/sendmail.mc > /etc/mail/sendmail.cf
-Install MailScanner using the provided install.sh and install
-Install SpamAssassin using the provided RPM files
-Install F-Prot using the provided RPM file
-Configure MailScanner by modifying /etc/MailScanner/MailScanner.conf
(look for these settings)
        MTA = sendmail (search for MTA =)
        Virus Scanners = f-prot
        Use SpamAssassin = yes
        SpamAssassin Auto Whitelist = no
        Delivery Method = queue
        Spam Actions = forward  address_goes_here
        High Scoring Spam Actions = forward  address_goes_here
-Comment out the following lines in /etc/MailScanner/spam.lists.conf
        #MAPS-RBL                       blackholes.mail-abuse.org.
        #MAPS-DUL                       dialups.mail-abuse.org.
        #MAPS-RSS                       relays.mail-abuse.org.
        #MAPS-RBL+                      rbl-plus.mail-abuse.ja.net.
-Edit /etc/sysconfig/mailscanner and change queuetime:
-Run the following commands:
         service sendmail stop
         chkconfig sendmail off
         chkconfig MailScanner on
         service MailScanner start
