Exchange 2007 POP3 Settings

I am trying to connect to our Exchange Server 2007(Not SP1) via POP from our SupportTrio system (an online website for users to submit their support tickets. Support tickets are emailed to a "Support" user on our Exchange Server. This SupportTrio is supposed to login to our Exchane Server via POP3 to retrieve these email). I am getting an error message, saying SupportTrio cannot connect to our POP3 acct.

I contacted support and this is what they wrote:
It appears that this POP account uses an unsupported method of authentication.   We support the following methods of authentication: APOP, PLAIN, USER, LOGIN, CRAM-MD5, and DIGEST-MD5.

Into which mode, do I have to set our Exchange Server 2007 POP3 to be able to support their authentication methods?

The following documents from Microsoft explain how to make changes to pop3 security in exchange.

( This is a link from the bottom of the first page)

It looks like from the email that you received back that you need to use a plain text authentication for the pop 3

I tried switching to plain text authentication. Exchange switched over successfully, but I am still getting an error message that I posted below. Is there a log somewhere on Exchange Server for POP to see if there is even any communication going on at all between my web host and my internal exchange server?

I would verify that the username and password that the supporTrio is trying to use is correct. Then check to see if you can use an outlook client or some other mail program to access the same account via pop3.  This will help to verify that the ports for the pop3 connection are not being blocked and you are able to get connected.
Do you have an further information on what the SupportTrio will support with the pop3 connection. Pop3 can be configured for SSL or TLS secure connections. If your Pop3 account was configured to use one of these secure method of connection and the SupportTrio does not support that it could be the cause of your failure to log on.
I also found the following that may be worth a try: (listed text below the link for convenience)

I've been running SupportTrio for a week now and I have absolutely no problem using the cron_pop . Here are some things I discovered in case they help you:

- cron_pop.php would not work when my account was using jailshell. As soon as I changed it to bash, everything was cool.

- I had to edit cron_pop.php and remove the "-q" from the first line.

- My POP server uses CPANEL. I had to use "APOP" authentication. "Auto" would not work.

- Be sure the cron_pop.php has the proper permissions. I set mine to 755.

- If you are having problems, log into your shell, cd to the directory where cron_pop.php is located and execute it from the shell. You might detect some problems this way. If it works from shell, then add it to your cron. I had the best results specifying it this way:

*/5 * * * * /usr/bin/php /full/path/to/cron_pop.php

Below is the solution that ended up working:

Changed POP3 authentication to PlainTextAuthentication, but it still didn't work on port 110. Checked that all usernames and passwords were correct. Then found out that GoDaddy Shared Hosting is blocking communication on port 110 and 995. Had to go with a dedicated server where port 110 and 995 was open.

Solution:
POP Server: ssl://mail.domain.com or ssl://xx.xx.xx.xx <--- public ip address of exchange server
Port: 995
