Browsing system logs noticed that bots trying to send mass messages from the server.
Attempts obviously not successful, however, exim queue filled up with emails like 1eiI0H-000693-V0 Message is frozen.
Below a very simple way to clear the queue with the specified message.
We log in to our server, then issue the command:
exim -bpu | grep frozen | awk {'print $3'} | xargs exim -Mrm
Messages are deleted.
The log can be seen perfectly exim.
cat /var/log/exim/main.log
