First, smtps (port 465) is deprecated, so you should use the
STARTTLS+submission port (587) unless there is a specific reason to use
smtps. The iPhone supports SARTTLS fine.

Next - there is absolutely no evidence that SMTP_AUTH is attempted in
your log snippet:

Enable the submission port in postfix (just uncomment the example), and
tell your iPhone to use SARTTLS on port 587.
