Can send Mail Outside Domain SBS 2003 IMAP

Greetings,

I have set up an account to access mail using IMAP for a specific software program we are going to be using. The account can receive mail from the outside but it can not send. I get the following error

Your message did no reach some ofr all of the intended recipients
The following recipient cannot be reached
550 5.7.1 unable to relay for <email address>

any help would be appreciated

You need to set up your email client to authenticate to your SMTP server (Exchange) for outgoing email.

1. Start > Control Panel (Classic View) > Mail > Email Accounts
2. Choose the IMAP account and hit change then more settings
3. On the Outgoing Server tab choose "My outgoing server (SMTP) requires authentication" annd "Use same settings as my incoming server"
4. Hit OK then OK and try again.
