Hi

I'¦ lanswer my own e-mail:

Server X has my server in its resolv.conf. 

Server X has runs Postfix and has "reject_rbl_client list.dsbl.org" in
the main.cf configuration file. dsbl.org does not exist any more. 

When my server is contacted, it takes some time to answer. On server X
a NAT router times out and refused the late answer. This causes the
log entry mentioned below. 

Removing the rbl entry in main.cf solved the problem. 

This investigation was made by Jørge nThomsen.
