Exim cheat sheet – Commands for  troubleshoot mail issues in cPanel/DirectAdmin or any exim mail server

Scenario:

Below are the most common Exim commands which help an Administrator to ease his life

Print a count of the messages in the queue:

exim -bpc

Print a listing of the messages in the queue (time queued, size, message-id, sender, recipient):

exim -bp

Print a summary of messages in the queue (count, volume, oldest, newest, domain, and total

exim -bp| exiqsumm

Print what Exim is doing right now:

exiwhat

To check if the server routes the mail properly use exim -bt

# exim -bt alias@localdomain.com
user@thishost.com
    <-- alias@localdomain.com
  router = localuser, transport = local_delivery
root@localhost# exim -bt user@thishost.com
user@thishost.com
  router = localuser, transport = local_delivery
root@localhost# exim -bt user@remotehost.com
  router = lookuphost, transport = remote_smtp
  host mail.remotehost.com [1.2.3.4] MX=0

Display all of Exim’s configuration settings:

exim -bp

exiqgrep

Its used for grepping through the  exim queue.

search the queue for messages from a specific sender :

exiqgrep -f  user@domainname.com

Search the queue for a specific recipient

exiqgrep -r user@domainname.com

To print messages older than the specified number of seconds use -o .

For example, messages older than 1 day:

exiqgrep -o 86400

To print messages younger than specified number of seconds use -y

Messages younger than one day can be listed  using the command

exiqgrep -y 86400

Print just the message-id of the entire queue:

exiqgrep -i

Exim Commands to Manage the queue

exim -q -v

exim -ql  -v

Remove a message from the queue:

exim -Mrm <message id >
