How to retrieve email? (Postfix / Courier)

[Merritt]

Well, I recently followed this how-to:
The Perfect Server - Debian Lenny (Debian 5.0) [ISPConfig 2]

First thing is first: Everything seems to be going beautifully, and I'd like to throw a big thank-you to falko for it. I am running my own site on my home server!

I have one question right now: In the How-to I installed Postfix & Courier for email. In ISPConfig I enabled maildir, and I believe I have correctly setup an email addy. I don't know if I'm too tired or what, but I am at this point: what now? I want to start handing out this email addy to people so they can contact me, so how will I get this? A pop client? What would the config for POP be? Did the web interface for Courier get installed?

I've managed to work my way through everything else, and everything else is working, this is, I believe, the last piece! Thanks in advance for any insights!
