Could anyone help me with a problem I deal?
I set up squirrelmail to work with sendmail and imapd in a SUSE ENTERPRISE LINUX 9.0 machine. I run
http://www.mysite/squirrelmail/
and the page shows up.

However, when I try to log in my root mail account, the following message appears:

Bad request: The IMAP server is reporting that plain text logins are disabled. Using CRAM-MD5 or DIGEST-MD5 authentication instead may work. Also, the use of TLS may allow Squirrelmail to login.
