I have just found an article, Ms Knowledge Base 310669 - "MS02-011: An Authentication Flaw Could Allow Unauthorized Users to Be Authenticated on the SMTP Service" if anyone else has suffered a similar issue. You can follow the links to download a patch, which I'll try this evening.

Message Relay is turned OFF but at various times in the IMS "Outbound messages awaiting delivery" there can be 20-30 e-mails going out with no originator. I know a firewall would go a long way to putting a stop to this, but there is no chance of money being spent on IT here. Great! Anyone any ideas?
