Sometimes we might face problems in receiving the emails in the inbox.While Checking the email logs we may find the error logs as follows :
/var/spool/exim/db/ratelimit: unexpected file type or format.
failed to open DB file /var/spool/exim/db/ratelimit: Bad file descriptor
H=xxx.xxxx.xxxx [1.1.1.1] temporarily rejected connection in “connect” ACL: ratelimit database not available
failed to open DB file /var/spool/exim/db/ratelimit: Bad file descriptor
H=xxx.xxxx.xxxx [1.1.1.1] temporarily rejected connection in “connect” ACL: ratelimit database not available
The above error is basically due to exim database on the server being corrupted. You can follow the steps to resolve this:
First stop the Exim service
/etc/init.d/exim stop cd /var/spool/exim
We will create a backup of the current exim DB.
# cp -R db/ db-bak # cd db/
After that we will remove all the files currently existing in the folder.
# rm -rf *
Now restart the exim service so the DB is auto created.
/etc/init.d/exim start
The emails should now work fine on the server !
