Using POP on Turing

Turing provides POP service using APOP authentication or SSL only. You can use turing as a POP server to remotely access your mail using a POP client on your remote machine which also supports the APOP protocol or SSL. For security reasons the normal user/password authentication is disabled on turing because it transmits passwords in plaintext. Instead, we use APOP, which is a more secure version of POP which uses a separate password for mail and does not transmit that password in cleartext, or SSL, which encrypts both the password and the emails. To set this up:

1. Check to make sure that your email client of choice supports the APOP protocol or SSL. Eudora supports APOP, as do many other email programs. Microsoft Outlook supports SSL. Check the configuration of your program of choice to see what protocols it supports. Do whatever you have to do to enable this feature on your email client.
2. If you are using SSL, make sure that you specify your incoming mail server as "turing.cs.hmc.edu" (warnings occur if you call it anything else).
3. If you are using APOP and have never set up an APOP password for your turing account, then log into turing and type "popauth" at the shell prompt. Enter a password to use with APOP. If you are prompted for your old password and you do not know your old password, send email to staffnow@cs.hmc.edu requesting that your current APOP password be cleared. Then log in to turing and type "popauth" at the shell prompt. Enter a password to use with APOP.
4. At this point things should be set up. Try it out. If it doesn't work send mail to staff and we'll help you with it.
