Answer 1

There are two completely different processes involved:

• Queueing the mail to your local MTA (This is what PHP's mail() does)
• This MTA delivering (with possible hops in between) to the final MTA, which delivers into the users mailbox

Obviously PHP only knows about the first step and may be right to consider it successfully done even if something else later goes wrong - e.g. the receiver domain simply not accepting your mail (which sadly is the new normal).
