Hello, i have a problem, i have exchange installed on my server, along with my webserver as well.

i can send emails using administrator@thedigitaldream.co.uk (mydomain) using outlook and they get to the recipiant fine.

But, if they send an email back, postmaster@thedigitaldream.co.uk replies saying that the message failed?

does anyone know what could be wrong?

Thanx

Have you created multiple smtp-internet email adresses with your account ?

Is the postmaster connected to your account ?

please PM or post a cpoy of the message and its headers here, we can then see if it is rejecting the e-mail or if it is not actually finding the server.

have you set the Primary Mail exchange for your domain to the IP address of your exchange server?
