In iOS 7, how can I easily specify an email address to be used as a FaceTime favorite?

Question

Something seems to have changed for the worse in iOS 7. Under iOS 6, it used to be possible to select various "identifiers" (email, telephone number) to be used for FaceTime for the same person, and these could be labeled differently. In iOS 7, when adding FaceTime favorites, one is given the option of adding the *contact* for FaceTime or FaceTime audio, but it isn't clear how to add a specific identifier for a contact.

Answer 1

Doing so will cause issues. If you send out mail which to an outside server appears to be non existent, mail may be rejected and you may even be blacklisted.
You can remove the account from WGM and add a role account as an alias send to /dev/null. This will look to the outside world like an existing address, but simply be discarded on your system. You should however include a working address in your mailings for people to be able to respond.
Assuming you use local domains, edit /etc/postfix/aliases and add:
noreply: /dev/null
(you can change noreply with the sender used in your PHP apps, but I'd probably change the PHP apps to use noreply as this signals to people receiving your mails that this address is unattended).
When done, issue:
sudo postalias /etc/postfix/aliases
sudo newaliases
sudo postfix reload
