Quite possibly they've found you doing it, and closed the hole in their
sendmail configuration, or restricted relaying to those hosts they trust -
which msot likely doesn't include you.

Do what you should ahve done in the first place - either write to the
SysAdmin at the destination and ask them for help fixing the problem, or
write to the SysAdmin at Telstra, explaining the situation and asking
permission to relay via them.

Relaying is the classic method of sending spam - and most sensible
SysAdmin's have closed the relay hole in the sendmail/Qmail MTA's to stop
it.
