[146.231.178.31]: can't verify header sender (try again later):
envelope sender is <phrg@???>
The wording of that message is accurate, but misleading. What Exim
cannot verify is any sender in the message's headers (that's what it
means by "header sender"). It isn't the envelope sender that is at
fault. (I have changed the wording a bit to try to make this clearer in
the next release.)
However, I see that the From: header contains
> F From: phrg <phrg@???>
which is the same as the envelope, so even if you misunderstood the
message, that doesn't matter!
The "try again later" bit means that an attempt to verify the address
got a "defer" result.

You didn't include the directors... since *.ru.ac.za is local, it will
have passed the address to them for verification. Problems in directors
can cause deferment.
(1) If you run the command
exim -bv phrg@???
what to you get?
(2) There aren't any silly non-printing characters in there are there?
