RE: pop3 over telnet and clear text passwords

["Roger A. Grimes" <roger () banneretcs com>]

Actually, POP3 by itself, without telnet being involved transmits logon
name and password in clear text...and like Telnet, it's kind enough to
precede the password with the PASS keyword (helps packet sniffing
crackers out).

If you've got Outlook/Outlook Express and Exchange, you can choose
Secure Password Authentication and it will not transmit the password in
cleartext.

Subject: pop3 over telnet and clear text passwords

I often use pop3 over telnet to check on email boxes some users have.(ie
that they've been setup properly) How do I mask the fact that the
username/password is transmitted as clear text?(If I can?) Thanks Murad
