Can postfix be configured to guarantee durable email receipt?
E.g., can it be sure to fsync the mbox/Maildir file and/or directory
No, but it does guarantee durability from the receiving SMTP session to
the delivering process.
This CAN be delivery to a mailbox.
before it acknowledges successful receipt of an email?
That would be the end of the SMTP session.
No MTA guarantees final mail delivery *before* returning the SMTP
