A customer at sbi.dk has no luck delivering mail to
mail.k.tera-house.ac.jp through our mail relay, mail.net.uni-c.dk.

Currently there are 875 letters queued for a user @mail.k.tera-house.ac.jp.
It has no MX, but an A record. mail.net.uni-c.dk has no trouble resolving
it. I just tried to generate a bounce by writing to
[EMAIL PROTECTED], but after three hours it has
not appeared here.

I cannot figure out where the problem is. Here is a bounce our
customer received.

Hi. This is the qmail-send program at mail.net.uni-c.dk.                    
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.         

<[EMAIL PROTECTED]>:                                            
Sorry, I couldn't find any host by that name. (#4.1.2)                      
I'm not going to try again; this message has been in the queue too long.
