Fedora 5. Can't connect to Sendmail or Dovecot outside internet network

My Sendmail & Dovecot sevices are running fine as I can telnet to them on the local machine. I have port forwarding setup properly as I have tested it on different ports. But when I come to telnet to port 25 or 110 from another connection it refuses the connection.
When I installed Fedora I disabled firewall so I don't think it's that. Is there something I have to alter in the /etc/hosts.allow file?

sendmail binds only for localhost, you need to change that.
vi /etc/mail/
search for the line which is making sendmail bind to (in vi just do / ), you need to add dnl to that line and then update your sendmail conf file.
m4 >
service sendmail restart
and in /etc/dovecot.conf, there is a line where it says the protocols you are serving, the line is hashed, remove the hash and restart dovecot.
