[Mimedefang] Help with relay=defang at localhost

[Bill Maidment]

Hi

I'm running MD 2.33 with sendmail 8.12.9 and SA 2.53 and I've just 
switched on quarantine notification, but nothing gets through.
I saw some mention at the beginning of the year about this, but I 
couldn't find a note of any solution. Everything else works as expected, 
but no notification email gets through. Trusted-users has defang in it, 
but I still get a warning on the log. I suspect relay=defang at localhost 
is a pointer to the problem, but I'm stumped. Log follows:
