configure Exchange for external email

I need to download a free email client that uses IMAP, then send email to a public email address, I want the email to go through our Exchange server 2010.
Free email Client for MAC would be the ideal, since I have MAC.
MAC has default MAIL, but  I cannot get it to configure for IMAP. the only way it works if I connect it straight to Exchange server 2010.
in my case I want to test if our Exchange server can relay email for authenticated users.

How can I achieve this?

Any help will be very much appreciated.

Thank you

I believe though it is not a Relay configuration that is needed...

if I am not wrong, it is how to get a NON exchange application to authenticate and Exchange users with SMTP.

Ahhh, ok. Then that would be a receive connector. You need to create a new Receive connector with proper permissions for anonomous senders.

See the below link on how to create a receive connector for anonomous senders.

Once you have the receive connector created/configured, you then need to add the IP addresses of applicaiton server or device that you want to allow send of emails.

I am going to simulate what users do:

Let 's say for instance you  have an Exchange mailbox
you are outside the company on your PC connected to internet, and you have a  form, and you fill out the following fields

Outbound Email Server(SMTP)

username: domainname\username
Email Password:

Click (Send Test mail)

in our case the connection fails, with error "Could not connect to SMTP Host"

I found out a user can connect to Exchange server using IMAP , but when sending he cannot send through Exchange server

Wow... I cannot configure IMAP account in Outlook...
I used NSlookup, the set type=MX, then typed our domain name
it gave me the Mail exchanger

so I used for Incoming and Outgoing Mail server(SMTP)

But still get connection to the server failed.
