I have been testing Mobility Pack and I cannot send or reply to email that are outside my domian. if I do the messages are bounced by my spam filter.

I have my spam filter setup as a gateway to accept inbound email and pass it to my groupwise server. I have setup very tight rules on the spam filter to deny emial to address not on the approved list. And the approved list is only our user email addresses. So when I reply to a user outside my domain it tries to relay that email through my spam filter and it gets denied becuase that email address is not on the approved list.

Is there a way around this? Can I set the SMTP server to something else on my client? or is there a way to inject the sent mail back into the GW system using sync so it can't be send from inside my network?
