2013-12-22 03:16:00 H=[184.108.40.206]:13468 temporarily rejected connection in "connect" ACL: ratelimit database not available
To fix these error , the exim cache database on the server needs to be flushed to stop this message.
Run the folllowing command on root:
[email protected] [~]# rm -fv /var/spool/exim/db/*
Then run the following command on root:
[email protected] [~]# service exim restart
If this doesn’t work , then run /scripts/upcp –force on the server and then check exim_mainlog for the changes.
