Hi Guys....was a bit early in my questions. Have just taken over as Admin of the groups Mail and am finding all the previous Admins did not set everything up correctly, Thanks for the response.

John,

 

I will be glad to assist you with this. Regarding the new accounts, you will want to create these under the Users section (Settings -> Domain Settings -> Users), users created here will then begin to receive mail directed to the desired address.

 

When you attempted to send to the newly created users, were you receiving bouncebacks with status codes you can provide ?
