chech your logs

cd /var/logs

then  more exim_mailing / grep email

you will get the error ,,,,,,,,,,,,,

then try to use the code below to fix the problem

This can be caused by multiple things, however if it happens for each email, it’s likely your exim databases are corrupt; to resolve this you should:

/usr/sbin/exim_tidydb -t 1d /var/spool/exim retry > /dev/null
/usr/sbin/exim_tidydb -t 1d /var/spool/exim reject > /dev/null
/usr/sbin/exim_tidydb -t 1d /var/spool/exim wait-remote_smtp > /dev/null

/scripts/courierup — force
/scripts/eximup –force

If you did that, yet the problem persists, you can either seek professional help, or contact the cPanel support.


OR  use below solutions

To solve this issue, you need to

  1. Login to with the account you use with exim4. It will ask you to login a second time with a captcha… do so
  2. login on all of your machine that use this technique and issue the following command :

    sudo exim -qff
