Clear VS Plain and other authentication methods

Question

I tried this setup, Jeff... gets me to the login page fine... but doesn't seem to recognize any of my email logins (all which are virtual).
I have a website setup as MAIL.MYDOMAIN.COM... port 80...performance cache OFF... and pointing to /usr/share/squirrelmail. I tried these settings with OPTIONS-->WebMail both checked and unchecked. Doesn't seem to make any difference.
However, I had disabled CLEAR in Advanced->Security->Authentication after reading another poster's comments regarding his server becoming a spam relay. Enabling CLEAR again made your SM setup work.
So, now.. what do I do to make this setup work with an AUTH scheme other than "Clear"? And how does "Plain" differ from "Clear"?
Thanks for the education.
As Alex mentioned, turn off the performance cache.
You can change the port in ServerAdmin to something
else (you mentioned 8010, which is fine).
You may need to create a seperate Site for Webmail if
you don't have one already.
To take this a step further....
My preferred (non-SSL) setup is this:
- Assuming you already have DNS of mail.domain.com
- Create a site for mail.domain.com (port 80)
- In Sites/General, port 80
- In Sites/General Web Folder
"/usr/share/squirrelmail"
- In Sites/Options, turn off Perf Cache.
If you do the above, when you hit
http://mail.domain.com
You will go straight to Squirrelmail without having
to add a /webmail to your url and without having to
use a different port #.

Since you disabled "clear", you will need to configure SquirrelMail to use Cram-MD5.
To do so run:
sudo /etc/squirrelmail/config/conf.pl
and adjust your IMAP and SMTP settings
