I have found the cause on my production system.

Symantec Antivirus, set up perform outbound port 25 email scanning - must
have had an update last night.

A Pity I can't get the lost costs back from Symantec, as this is a share
transaction service, and on reboot it duplicated the outbound emails which
were transaction requests to brokers - only minior swings in share pice but
still £000s went today!
