You may not need to change to different client software. It also doesn't
matter if there is Mac specific support on the NT server. There are many
email servers out there, quite a few of which run on NT. What counts in this
instance is the protocol you're using to connect to the server. It sounds to
me like you're connecting using POP3, which is a TCP/IP (Internet) standard,
not an NT specific protocol.

If you are using POP3 to connect to the server, you can use the preferences
for Claris Emailer to solve the problem. In the Emailer preferences for your
account, look for the option to leave a copy of messages on the server.
Remove the checkmark next to that option. If I recall correctly, you may
also specify a time frame for leaving a copy of the message(s) on the
server. Note that it has been more than a year since I used Emailer, so I
don't know the exact location in the Emailer prefs to change this, only that
it does exist.

As an aside, this is one of the differences between POP3 and IMAPv4. IMAP
will only download a copy of the headers of a message when you initially
connect. Then IMAP will download the entire message only if you select the
message based on it's header info, usually the subject line. With POP3, you
get the entire message as soon as you connect to the server. IMAP will leave
the message on the server unless you choose to delete it from the server.
POP3 will *normally* remove the message from the server once it has been
downloaded to the client. In many modern (and some older) POP3 email clients
there is an option to leave a copy of the message on the server. Note that
this doesn't prevent the entire message from downloading to the client, only
that it leaves a copy on the server for later retrieval.
