Hi,
One of our client facing issue with mail "remote_smtp defer (-53): retry time not reached for any host".
Simply take backup of "/var/spool/exim/db/" directory if there is another problem arise.
Stop exim service using below command.
Quote/etc/init.d/exim stop
Then use below command to access db directory.
Quotecd /var/spool/exim/db
Now delete the ratelimit & retry files by using below commands.
Quoterm -rf ratelimit
rm -rf retry
Or delete all files from "db"directory by using below command. As above steps we have already taken backup of "/var/spool/exim/db/" directory if there is another problem arise.
Quoterm -rf *
Then start the exim service using below command.
Quote/etc/init.d/exim start
That's all. :)
