Saw this product a few weeks back and I've got it installed. I'm really impressed. I'm planning on releasing this into a private school that I work at. However, I have a question. Is there a way that I can setup the SMTP relay through my ISP to use some sort of authentication? I'm still learning the ropes in regards to email in the Linux world so any help is beneficial. I've got this up and running on Fedora 4. Everything else is working fine, it just sends an email back saying that my SMTP server needs authentication.

Great product and great support. Keep up the great work!!!
