Notes on POPmail
----------------

POPmail is a full-featured email program, with menus, windows, mouse
support, and online help.  There are also a few "extras," like a primitive
telnet, finger, nslookup, and webster (see below on the last one).  The
documentation is quite good.  POPmail requires DOS 3.0 or later; EMS and a
mouse are helpful, but not required.  You should have the packet driver set
up and connection established before you set up POPmail.

To use POPmail in a dynamic IP setup, you must use Dospppd as your packet
driver and set up POPmail to use BOOTP (it uses BOOTP by default).  There
does not seem to be any other way to get it to work in the dynamic IP case. 
POPmail has a bug in its BOOTP support, and only Dospppd includes a
compatible workaround.  The MYIP variable is not used.  There is supposed to
be RARP support in there somewhere, but I haven't been able to find it. 
Minuet can be used for email and is probably preferable anyway.

To configure POPmail, select the "Network..." option in the Setup menu.

Set "User Name" to your userid as assigned by your Internet provider, and
set "Password" to your password.  This is the username and password of your
POP account, if different from your regular username and password (on Agate,
they are the same as the regular ones).  The Password is case-sensitive and
does not echo as you type it, so be careful.

"Host Computer" is your POP/SMTP server's name.  They need to be the same
machine for POPmail; it is possible that they are the same machine with
different names, in which case POPmail will still work.

If you have static IP, set "Microcomputer IP address" to your PC's IP
address as assigned by your provider.  If you have dynamic IP, leave
"Microcomputer IP address" blank.

Set "Subdirectory for Mail" to the directory where you installed POPmail.

If you have static IP, set the 1st IP address for "Gateways" to the IP
address of the machine you dial into; with dynamic IP, leave "Gateways"
alone.

If you have static IP, set 1st IP address for "Name Servers" to the IP
address of your provider's name server; with dynamic IP, leave "Name
Servers" alone.

You may have to set a couple things in Advanced, so click on that.  Set
"Preferred full name" to your (human) name.  Set "Reply-to address" to your
email address.

If you have static IP, set "Net mask" to your provider's netmask, or set it
to 0.0.0.0.  Make "Net mask" blank (or leave it alone) if you have dynamic
IP.

You might want to increase "Retransmit timeout (sec)".  I have it set to 10.

"Max transmit unit in bytes: MTU", "Max segment we can receive: MAXSEG", and
"Most bytes we can receive without ACK" should all be set to 512.

If your provider has a POP-3 server rather than POP-2, as most ISP's do
nowadays, you will need to change "POP port" from 109 to 110.  POPmail may
be the only DOS email client that supports POP-2, which is very rare. 
Assume your provider has POP-3 unless they tell you otherwise.

The rest of the Advanced settings should be OK.  Click on OK in the Advanced
box, then click on OK in the Configure box as well (or tab to the buttons
and hit <enter> if you don't have a mouse).

As noted above, with dynamic IP you must use the Dospppd packet driver.

In the (<alt>-<space>) menu, there is an item called "Webster".  It is
useless.  There are no publicly-accessible Webster servers any more.  If you
know of one (perhaps available to students at your college), you can of
course put it in.

You can read your mail offline, and you can compose one reply at a time
offline.  When you exit POPmail, whatever was in the Compose window, if not
sent, gets remembered for next time.
