Setup Unix mail imap with K-9 app on Android.

Android 4 default mail application has problems working with CS IMAP mail service.

To work with CS IMAP service, please install K-9 free application from app store.

It recommended that you login to CS webmail before K-9 setup, to make sure you have the correct username/pw and have mail in inbox.

K-9 setup for IMAP access:

  • Make sure you are connected to the internet.
  • Create an account with the following important parameters:

o For Fetching mail / Incoming mail server:

  • Address:
  • Password: Your CS Unix password.
  • Account type: IMAP
  • IMAP Server (Fetching mail, Incoming mail server): for faculty staff or for TA
  • Security: SSL/TLS(always)
  • Port: 993
  • Username: your CSA/CSM Unix username without
  • Password: The above password.
  • Port: 993
  • No Client certificate
  • Uncheck “Auto-detect IMAP namespace
  • IMAP path prefix: your mail account directory on CSA/CSM where you keep your mail (example: mail). If you have big homedir, and not set mail dir, it may fail. Please keep your mail folders in a separate mail directory called “mail“, which is the default for many mail clients.
  • Now it will check IMAP connection. If OK, it will continue to Outgoing server.

o For Sending Mail / Outgoing server:

  • SMTP server:
  • Security: SSL(always)
  • Port: 465
  • Require authentication
  • The same username and password as above.
  • Next to end Outgoing server setup.

Now you should see your incoming mail.

Enter Setup, enter the account setup, Folders.

  • In Folders setup, make sure Sent Items folder is set to the folder you want (best is Sent folder).

You should see your Inbox. If you have a problem, please open a request in Helpdesk for additional help.
