Is there a way to restrict sending an email to a pre-defined destination only?

I would like to send some info from within the app per email - but restruct the recipient list.

I know when sending emails the standar开发者_如何学Pythond email-dialog opens. However, is there a solution anyway? Possibly somehow intercepting the "Send" Btn and at least check the recipient list.

No, you cannot do this. iOS requires that the user controls the final setup of an outbound email for security/trust reasons. If you're asking for undocumented workarounds, someone (not me) might know one, but your app won't be App Store-eligible if you find one.

As commenter @Rog says, if you send email via your own server, you can do this however you want without Apple's restrictions.
