Yeah? Now reply to someone with the appropriate From/Reply-To addresses from that mashed up gmail account. Thunderbird does this seamlessly, figuring it out from who the email was To if possible. That's why I still use it.

You can add POP/IMAP and SMTP accounts and read, write and send emails directly in Gmail with the proper headers (i.e. no the "delivered by gmail.com" message on your emails.)
I can't use my domain with Google Apps now, so I use my domain registrar's mailboxes and SMTP servers from my Gmail account for the same effect.
