How to configure Exchange server email ?

I am using SMTP for sending email in .net build application.
But recently one of my client gave me the following exchange server details

Exchange server name :

and email id :

asked me to use this in the application.

But my application not running in the domain and the users using local machine login and using the application.

But i believe that if i want to use the exchange server the machine should be login in the domain.
Is this correct ?

What is different between using SMTP and Exchange server ?

Can i able to send email In my application if i use the exchange server name and email id without changing any coding ? OR i need to change the code for to use exchange server ?

It is not necessary that the pc should be in domain to use exchange.
Just configure port 25 i.e. SMTP protocol which is used for sending email.
and configure authentication, That's it

client gave me the following details to configure EMAIL

Exchange server name : exchange05.myserver.local

Email id : ersemail@aa.com
password : XXXXXXXX

But when i execute the following code

MailMessage message = new MailMessage("aaa@aaa.org","aaab@yahoo.com"," test","test");
SmtpClient emailClient = new SmtpClient("exchange05.myserver.local");
System.Net.NetworkCredential SMTPUserInfo = new System.Net.NetworkCredential("ersemail@aa.com","XXXXXXXX");
emailClient.UseDefaultCredentials = false;
emailClient.Credentials = SMTPUserInfo;
emailClient.Send(message);

asp.net
<system.net>
<mailSettings>
<smtp from="ersemail@aa.com">
<network host=" exchange05.myserver.local" port="25" userName="="ersemail@aa.com" password="XXXXXXXX"/>
</smtp>
</mailSettings>
</system.net>

i got this error message :

Mailbox unavailable. The server response was: 5.7.1 Unable to relay

please let me know how to fix this ?

Since my application using asp.net should i need to configure the SMTP in IIS7 ?

please let me know
