I have ntmail installed and i can pop and send mail to the default account
it created called root.
I installed the ntmail dll per your text file but i didn't know what to do
with the registry setting of HKEY_LOCAL_MACHINE\Software\IEA\RadiusNT\EISD
It refers to the External System ID for Emerald Administrator 2.2, i'm
runing 2.1 of administrator and 2.18 of the client.
The log files for ntmail say this (pop3 and Smtp)
Could not attach to emer_ntm.dll.
Of course the mail client won't authenticate through the db.
Let me know what other info would be helpfull.
