Please log in as root and run the following commands:

service sendmail status

chckconfig --list sendmail

netstat -ntlp | grep :25

iptables-save

grep -v '^#' /etc/hosts.{allow,deny}

We'll be able to see which process is listening on smtp port and if it's
not being blocked by either the packet filter, nor tcp_wrappers.
