Can you telnet to port 25?  For example, if your application IP name is 
smallufo.com, you should be able to give the command

telnet smallufo.com 25
and the mail server should reply with something.

For example:

jeffsilverman@jeffsdesktop:~$ telnet smtp.gmail.com 25
Trying 2001:4860:8005::6d... <=============================== this is an 
IPv6 address, you will probably get an IPv4 address
Connected to gmail-smtp-msa.l.google.com.
Escape character is '^]'.
220 mx.google.com ESMTP ud10sm27733287pbc.25

If you see that, then sendmail is running and listening to the internet.
