Topic: I need some suggestions or a contrib I haven't found

[timlitw]

We host some web site for some of our customers - some of those we host the email also and some have thier own email servers.  

We are changing some servers around and I needed to move some site off the web server to somewhere else temporary.  The SME server seemed like the perfect place. So I moved one site there to test. The site works fine but we can no longer send email to that client as the SME server insists that it is the MX for that domain.  

Is there a way to turn that feature off per domain hosted?

As you state your need is only temporary, the easiest way would be to set your e-mail client to use your ISP SMTP server and not the SME server for outbound mail. Depending on your SME version you may have to disable SME's transparent smtp proxy.
