Hi,
I don't know how I achieved this, but this is what I found in the log of
a postfix server submitting mail to my main exim4 server:
Mar 24 23:39:51 tiger postfix/smtp[3814]: BB856100A640: host

451 gave DEFER: ldap_result failed: 81, Can't contact LDAP server (in reply
So, it looks as though when LDAP server is unavailable, exim spews full
LDAP string substitutions to the client, including passwords!! I've not
been able to reproduce this yet though.
The system is a soon-to-be-upgraded Debian etch installation with:
