a sender does not come through by email.
There are no entries in the quarantine or data control report either.
So Sophos never received it.
The sender gets the following message:
Hi. This is the qmail-send program at *.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.

Giving up on 22.214.171.124.
What else can we do?
