Hi,
Been searching the web and haven't found solution for this yet, I've got my web server on a DMZ, and use a 3 homed network (external, internal and dmz) ISA Server my mail server can get and send normal SMTP, but while testing DNN's, i get 'SMTP failure'.
Any ideias?

I'll try anything, since the site must be up and running in 3 days.
