Subject: What happens when mail is addressed to "foo>com"

Here's a wierd one, the connecting server tried resubmitting this all night. In the end I had to blacklist the From address to make it go away. The sysadmin of blackhole.unosoft.co.uk later said his customer was trying to mail "msg.de" but had addressed it to "msg>de" by mistake.

I do have a similar domain here, "msg.co.uk", but how blackhole.unosoft.co.uk got here is beyond me. However I think SIMS should have replied with a 5xx error as that domain could not possibly exist:
