email - popping from exchange 2007

I'm having issues getting a linux box to pop from exhcange 2007.

This all started while setting up osticket. Once I had everything configured I get an invalid username/password them attempting to test the account settings.

I installed pop3test on ubuntu and found that the only way I can use it to get a clean login test is with the following command.

pop3test -a username -i mailservername
which outputs this:

S: +OK The Microsoft Exchange POP3 service is ready.

S: +OK

I've found a permanent fix for this issue here: LINK

It lets you disable TLS in the PHP mail client that osticket uses.
