I'm having an issue with how iOS 6 is handling "replying" of emails when I receive emails on my alias email. Instead of replying from the Alias, by default it's replying from my main iCloud account email, even when replying to emails sent to my alias email. Interestingly, on the mac side using Mail in OSX it replies fine from my alias, it's just not doing the same from my iPhone. When replying from my iPhone I have to manually go into the "From" field and change it to my alias email, for every single reply. This is a bug, correct? Or is there a setting I'm missing somewhere. Any help is appreciated.
