In ubuntu their are various options and i would suggest to check once with chkconfig, 
 
sudo apt-get install chkconfig 
 
It can be used via CLI chkconfig, showing list of On/Off jobs. Also we can view system services using chkconfig –list 
 
Services can be turned on using 
 
chkconfig &lt;service&gt; on 
 
Services can be turned off using 
 
chkconfig &lt;service&gt; off 
 
And we can even add our own service, using a proper init script with proper headings. 
 
chkconfig --add &lt;service&gt;

Xeams Smtp Server Status is Not Running and Smtp Proxy Server Status is Unknown

Within Internet message handling services (MHS), a message transfer agent or mail transfer agent (MTA) or mail relay is software that transfers electronic mail messages from one computer to another using a client–server application architecture. A MTA implements both the client (sending) and server (receiving) portions of the Simple Mail Transfer Protocol (SMTP). The terms mail server, mail exchanger, and MX host may also refer to a computer performing the MTA function. The Domain Name System (DNS) associates a mail server to a domain with mail exchanger (MX) resource records containing the domain name of a host providing MTA services.
