Use Gmail to fight spam

Haven't tried yet ....

Created a new Gmail account. (I already had one, but I wanted a second that was exclusively dedicated to my domain's mail.) Clicked Gmail's Settings link, then headed to the Accounts tab. Clicked Add another e-mail account and configured Gmail to fetch messages from my domain's servers (and to not leave copies there, otherwise my server would eventually get full and start rejecting messages). Presto: Gmail automatically scans for spam when it retrieves mail from other servers, so I could have stopped right there. However, I didn't want browser-based Gmail to be my primary destination for e-mail activities, as I prefer to use Outlook on my desktop and my cell phone for on-the-go messaging. Therefore, I headed to Gmail's Forwarding and POP/IMAP tab and enabled IMAP, which allows for two-way communication between Gmail and other mail clients. Finally, I followed Gmail's configuration instructions for setting up IMAP with Outlook and other clients.

Now, when I receive e-mail via Outlook or my phone, it's totally transparent: There's no evidence of Gmail's involvement-except for the total lack of spam, which gets filtered out along the way (and stored in Gmail's Spam folder, where you can easily review it for false positives).
