I use Fastmail which allows me to have a catch-all with my own domain name. I don't need to set anything up to give out a unique email address I make up on the spot. I highly recommend this method.

The flipside of this is that it's extremely easy to spam you by just iterating new email addresses.

		I do it and never had an issue. I get odd emails every now and then with an unused address, for services/people I never contacted though. But I'm talking about perhaps 2-3 per year.
