Whoa! You are right on the first two anyway. That's what I get for answering
email so late at night.
My first guess is you mean SMTP, but...
Yes.
...
SMTP is used to *send* messages, not *get* messages.
You apparently mean POP or IMAP or some such.
POP.
...
telnet client does not echo what you type.
...
This is true only of broken (or misconfigured) telnet
clients.
Gee, I just open a DOS command window & type telnet. It doesn't have any
options.
...
