Server is Fedora 4 running POSTFIX:
I can send emails to my server and have found that they ARE actually on my server but I am unable to read them.
Maildir has been switched both on and off for testing and is currently ON.
Although there are MX records in the DNS (added manually to force public IP), there are none shown in the DNS Manager -> Site -> Records area.
When I login using webmail I've noticed that there is no quota indicator as there was on a previous installation which would seem to indicate that I am not logged in "correctly".
