I use my own domain for email, so that I can use multiple email addresses when shopping online, subscribing, etc.
These are all redirected to Gmail.
I have created some addresses under that domain for use when sending in Gmail.
What I would like to do is send mail without the need to register each address separately, or create a new email address in "Google Apps for your domain".
Is there a method to register the whole domain with Gmail so that I can send email in this way without needing to verify a new address?
[Original answers suggested Google Apps for your domain. I didn't known about this, and I think it will be useful for me, but it doesn't obviously allow this feature.]
