I have 3 packages that reports being in ZA according to overseas PO, but 2 of the 3 shows the SAPO misspelled incomming (double m...so bad) message, so I would say it depends.
Complete message is "JHB INT MAIL CENTRE (HUB), Incomming International".
You're lucky, mine were recorded in JIMC but now reflecting this message, like they're in a black hole.
