Great news James

Some people may not have seen an email from me for a while.

Both Onno and I have a DKIM policy that requested modified emails from us are 
rejected.

This meant that gmail and others would dutifully fail to deliver our mail that 
had been rewritten by the PLUG mailing list.

The new iec.plug.org.au server does some header rewrite magic and replaces the 
DKIM so messages say:

From: Harry McNally via plug <plug at plug.org.au>

If you want to use strict DKIM policies then PLUG will now deal with them 
politely.

All the best
Harry
