Since we're at it with the resending issue, here goes another one.
It's not the first time I get a message like this:
Hi. This is the qmail-send program at csor.pair.com.
I'm afraid I wasn't able to deliver your message to the following addresses.
This is a permanent error; I've given up. Sorry it didn't work out.
This message is looping: it already has my Delivered-To line. (#5.4.6)
Is it my mail server or is it the list?
