Ok I have this set up with domain contoso.com (you wouldnt know I`ve got through numerous MS training kits eh).......it is working fine for mailing between users internally, however I now want to set up users with an Internet domain name email address. I have set up internet domain name to point MX record @ my WAN IP and forward port 25 to mail server which I ahve adn entry in DNS to reflect that it is mail server for *** internet domain etc. I thought it would then be simple to configure an SMTP connector to send email out via my ISP but ti doesnt seem to work.........I *thought* that this connector would present just like a client such as outlook etc sending mail via smtp......hm doesnt seem to work, anyone any advice?
