I'm pretty damn impressed with how sophisticated my new crack berry is. However I'm a might puzzled.
I own a domain which runs a number of web applications for personal use. I performed my BIS Email setup using an Email address available through that domain. I was surprised that it didn't ask me for my POP3 settings, and has no issues pushing my emails
Just where did it find my settings O_O

BIS queries the MX record for your domain name and uses that to make assumptions as to what your POP3 server might be. It tries a handful of possible options until it finds one that works.
If it can't find one, then it will prompt you to enter one.

It's pretty easy to guess POP settings in most cases.
