I generally use Google Apps to handle email domains. I'm unfortunately stuck in an infinite loop with Google  for one the domains I recently picked up. Right now I use Zerigo's awesome DNS services. How can I get email@example.com forwarded to my Gmail account? Better yet if this is a free/cheap solution and can work with multiple aliases going to different real email addresses (firstname.lastname@example.org -> email@example.com, firstname.lastname@example.org -> email@example.com)
 Long story. I alternate between "Sorry, you've reached a login page for a domain that isn't using Google Apps." and "This domain has already been registered with Google Apps." Seems like many others are having this issue and Google isn't doing anything about it.
