You need to configure the Java mail to talk to a mail server. I doubt you have mail server on your local machine. Moreover, Mail servers usually accept SMTP connections through 25 port.

if you use Spring, you can send email  by it Classes.
Firstly, you must set some beans as you can see below:

<bean id="mailSender"
class="org.springframework.mail.javamail.JavaMailSenderImpl">
<property name="host" value="${hostname}"/>
<property name="username"
value="${username}"/>
<property name="password"
value="${password}"/>
<property name="port" value="25"/>
</bean>

<bean id="mailMessage"
class="org.springframework.mail.SimpleMailMessage"
singleton="false">
<property name="from"
value="orodsem@..."/>
</bean>

If u r using outlook in office to check mails......its easy to find this.

open outlook... goto Tools...account
here in properties..check server IP..its ur smtp  server.
and port is 25 for smtp..!!

u can use google smtp  server for test. it's free.
set host  = smtp.gmail.com and port = 465.
make a new account in gmail and set username and
password to it.
set auth = true.
set sslsocketfatory = true.
u can find samples about it in internet.
