I have a Google Apps account for mail.example.com, but actually use addresses @example.com (e.g. tony@example.com, whereas the account is tony@mail.example.com). This isn't ideal, but I'm stuck with it for now.
In iOS mail I have this account setup as an Exchange account (i.e. not IMAP), which means that there isn't much in the way of settings. Email I send from this account comes from tony@mail.example.com, which works, but I would prefer tony@example.com (this already works fine on the Desktop/browser).
Is it possible to change the sender/from/reply-to header in this situation?
(I wasn't sure whether this was an iOS mail issue and so should be asked here, or a Google apps issue and so should be asked on webapps.se, or if it's just not possible. Feel free to bounce me if appropriate!)
