Linux / Unix : Important Exim Commands

Exim is a message transfer agent (MTA) for hosts that are highly comfortable and running in Unix or Linux Operating system. Exim server is developed at the University of Cambridge. We can easily manage and configure in server . In this post have shared few executable commands as below,

1.Find out number messages in queue:

# exim -bpc

120

2. List out all the messages from the queue

# exim -bp

1m   37K 1WsaJy-003biD-Kv <root@host.hostname.com>

          user@domain.com

3. Count the number of messages for each email id

#  exim -bp|grep "<"|awk {'print $4'}|cut -d"<" -f2|cut -d">" -f1|sort -n|uniq -c|sort –nr



  138 root@host.hostname.com

    6 admin@domain.com

We can easily count the number of sent  messages  for every user

4. View specific email logs

# exim -bp | grep 'username@domain.com' | awk '{ print $3; system("exim -Mvl "$3)}'



1WsQ3G-0004k4-4k

2014-06-05 10:47:22 Received from username@domain.com H=localhost…

5. Forcefully sending message from a domain

# exim -v -Rff  domain.com



LOG: MAIN

  cwd=/home 4 args: exim -v -Rff domain.com

LOG: queue_run MAIN

  Start queue run: pid=3152 -qff -R domain.com

6. View message content

# exim -Mvb 1WsQ3G-0004k4-4k        

             

1WsQ3G-0004k4-4k-D

GOOD DAY.
