Thanks people.
There was a further update to courier last night and the problem has now
disappeared. Still don't understand why only some people were affected.
I was personally never affected - even though mail to one customer was
also forwarded to me - she had this problem and I didn't.

Hi folks,
I'm pulling out my hair... I have a strange e-mail problem. I'm hoping this
community can help.
I run an ISP in South Africa. Servers are all Linux Gentoo. I use EXIM and
Courier-IMAP/POP to deliver emails to about 3000 users using about 400
different domain names. From Monday the 28th October, a few clients - 10 so
far - are sometimes getting the following....
Begin forwarded message:
*From: *Mail Delivery Subsystem <postmaster>
*Subject: **Cannot display Unicode content*
This E-mail message was determined to be Unicode-formatted
but your E-mail reader does not support Unicode E-mail.
[...]
The error seems to be generated by courier. It can be found in its
sourcecode:
