A friend of mine just told me that he can't send mails to accounts on one of my servers via the SMTP server provided by his ISP.
The error message in the bounce he gets reads:
Hi. This is the qmail-send program at aon.at.
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…
