Hi Mark,

WRT POP3 commands -- I have two POP3 accounts, one with my current ISP 
and another [without SMTP server access outbound] from my previous ISP 
[they allow that hoping I'll return! :-) ], and although most of the 
POP3 commands work identically on both via Telnet to port 110, with one 
I have to enter e.g.:

"top 23 500"

with the other I have to use "top 23,  500"
neither use the form "pass_ ", but use "pass
"!

This is the extracted list of POP3 commands _I_ have a requirement for:

"telnet -p 110 "

POP3 is an open Internet standard. The common POP3 commands
and responses are listed in the following table:

Command              Responses

getwelcome ()        Gets the greeting from the server.

user (username)      Login with a username. If valid username,
                      server will respond with request for password.

pass_ (password)     Send password. If valid, server response will
[no "_" at *my* ISPs]    be two numbers, message count and mailbox size.

stat ()              Get the mailbox status. Response is two numbers,
                      message count and mailbox size.

list ([message])     Get list of messages. An option "message" gets
                      information on a specific message.

retr (message)       Get message number "message".

dele (message)       Delete message number "message".

rset ()              Remove all deleted message markings.

noop ()              No operation. Do nothing. Really. Needed in
                      unusual programming situations.

quit ()              Quit. Commits all changes, unlocks the mailbox,
                      and ends the server connection.

top (message, lines) Gets just the first "lines" number of lines of
                      message number "message". Useful on low bandwidth
                       lines to get just the first part of long messages.

uidl ([message])     Gets a unique id list -- a message digest including
                      unique ids. The option gets the unique id for the
                       specific message "message".

real example
telnet -p 110 pop.dodo.com.au

Command              Responses
getwelcome ()        Gets the greeting from the server.

                      server will respond with request for password.

                      be two numbers, message count and mailbox size.

                      message count and mailbox size.

                      and ends the server connection.
top (message, lines) Gets just the first "lines" number of lines of
                      message number "message". Useful on low bandwidth
                       lines to get just the first part of long messages.
uidl ([message])     Gets a unique id list -- a message digest including
                      unique ids. The option gets the unique id for the
                       specific message "message".


The "titles of the Telnet objects in folder
"TelnetPN to: Mail Accounts"

are respectively:

Telnet Austarnet POP3 Mail
[DON'T use commas]

and

Telnet Dodo POP3 Mail
[use commas!]

so those cautions are in the Window Title whilst running!
