I started my new job two days ago, and it is my first Administrator position, as I am fresh out of College, with a little field experience in the past. Also, I'm new to your forums, so I'd like to say hello to everyone! Anyway, I'm glad to be getting hands on experience in Linux once again, and would like to take this opportunity to say that ZCS is a great product.
After installing ZCS, I logged in and created two user accounts to test if they could send email back and forth. Now, this could be a vague/broad question, but when I send an email, it's not reaching its destination. Mind you, I don't have DNS set up. Would DNS be the main cause of the emails not being received? Also, are there any other factors which could effect this?
