Can I zap addresses from my Gmail auto-complete list?

It's not easy, but you can delete addresses from your Google Gmail auto-complete list. To do this, click on the Contacts link on the left side once you're logged in to your Gmail account.

Then click All Contacts:

If you're like me, you'll find that Gmail has grabbed tons of email addresses and dropped them into the contact list. Definitely a drag.

If you want to just delete one or two, use the search feature to find them, check the adjacent box, and delete them. Tedious, but effective.

If you want to delete a class of addresses, like everyone who uses Hotmail, search for "hotmail.com", then once you have your set of matches, scroll down to the bottom and notice that there are two shortcuts:

Click on All then if there are a few you want to retain, uncheck those before you click on the "Delete" button.

Finally, if you've had it and want to delete everyone in the contacts list, simply scroll to the bottom of the "All Contacts" list, click "All" and select "Delete".

Unfortunately there's no smart filtering system for managing this, no "select all addresses to which that I have never sent a message", though that'd be darn cool. Or just ignore it all, which is what I do.

Hope that helps you out!
