Firts of all what type of email server are we talking about? I don't think the 1060 has the ability to authenticate (sort of like having a user name and a password on the email server). There are workarounds though. There is a setting within MS Exchange that allows you to set it where the IP Address of the 1060 is recognized and allowed to pass (see attached). We have had other situations where we had to use a freeware program called ArgoSoft to relay the emails to the mail server.
If you need to explore the ArgoSoft option let me know...a couple of my guys have played with it quite a bit.
Thanks!
