Mystery solved! It was all a bit more innocuous than it first appeared. There were two messages stuck in the inbox of my POP server, which because they had malformed return address could not be downloaded nor deleted from the pop server, so there they stayed, unread by anyone. Postfix was writing a message to the log complaining about the malformed address.
I was able to web mail into the pop server directly, and after a bit of fiddling with the unfamiliar interface, managed to delete them They were just the usual run-of-the-mill Nigerian-style scam letters, nothing to be too worried about.
