We can use the following commands from the shell to manage mail Queue in Exim Cpanel.
#exim -bpc Print a count of the messages in the queue:
#exim -bp Print a listing of the messages in the queue (time queued, size, message-id, sender, recipient)
#exim -bp | exiqsumm Print a summary of messages in the queue (count, volume, oldest, newest, domain, and totals):

#exim -bt email@example.com Test how exim will route a given address:
