I've built up a couple of exim boxes to replace some sendmail
mailrouters. I've got it setup to mimick the sendmail servers while I
work on the transition.
I had them running in the group and everything seemed to be working
fine, except about 3 times a minute, I would get an error message
"DEFER:ldap search initiation failed".
I've checked the addresses that failed, and they are just random
addresses. Some exist, some don't etc etc. We've checked the ldap
server to see if it saw any problems, and it saw no attempt to even
connect.
I ran the server with a -d-all+lookup and got a session that failed.

I'm not sure where to go with troubleshooting this further. Does anyone
have any suggestions?
