2009-07-20 21:58:07 Failed to get write lock for /var/spool/exim/db/ratelimit.lockfile: timed out
2008-07-20 21:58:07 H=[xx.xx.xx.xx] temporarily rejected connection in “connect” ACL: ratelimit database not available

To fix such an error , the exim cache database on the server side needs to be clear off to stop this message.

Run the folllowing command on root :

root@lolwut [~]# rm -fv /var/spool/exim/db/*

Output :

removed `/var/spool/exim/db/ratelimit’
removed `/var/spool/exim/db/ratelimit.lockfile’
removed `/var/spool/exim/db/retry’
removed `/var/spool/exim/db/retry.lockfile’
removed `/var/spool/exim/db/wait-dk_remote_smtp’
removed `/var/spool/exim/db/wait-dk_remote_smtp.lockfile’
removed `/var/spool/exim/db/wait-remote_smtp’
removed `/var/spool/exim/db/wait-remote_smtp.lockfile’

Then run the following command on root:

root@lolwut [~]# service exim restart

If this doesn’t work , then run /scripts/upcp –force on the server and then check exim_mainlog for the changes.
