Introduction

The information below can be used to adjust the Exim directive Delivery behavior for suspended cPanel accounts from the Command-Line. If you are looking to perform this from the WHM Exim Configuration interface, please review the article:

How-To modify the email behaviors of suspended accounts. 

Procedure

Before making any changes to any raw files it is recommended that you backup those files. The commands provided below include a backup element, but you are welcome and encouraged to first backup the existing Exim configuration using the information outlined in our documentation here:

Exim Configuration Manager: Backup

Choose the option below you wish to use, and be sure to copy/paste the commands precisely as written below:

Accept and queue messages:

sed -i.bak 's/^suspended_account_deliveries=.*$/suspended_account_deliveries=queue/' /etc/exim.conf.localopts;
sed -i.bak 's/^\*.*/\*\: \:queue\: Disabled recipient address/' /etc/exim_suspended_list;
/scripts/restartsrv_exim

Reject messages at SMTP time:

sed -i.bak 's/^suspended_account_deliveries=.*$/suspended_account_deliveries=block/' /etc/exim.conf.localopts;
sed -i.bak 's/^\*.*/\*\: \:fail\: 525 5\.7\.13 Disabled recipient address/' /etc/exim_suspended_list;
/scripts/restartsrv_exim

Accept and discard messages:

sed -i.bak 's/^suspended_account_deliveries=.*$/suspended_account_deliveries=discard/' /etc/exim.conf.localopts;
sed -i.bak 's/^\*.*/\*\: \:blackhole\: Disabled recipient address \(discarding\)/' /etc/exim_suspended_list;
/scripts/restartsrv_exim

Deliver messages normally:

sed -i.bak 's/^suspended_account_deliveries=.*$/suspended_account_deliveries=deliver/' /etc/exim.conf.localopts;
sed -i.bak 's/^\*.*/\*\: \:unknown\:/' /etc/exim_suspended_list;
/scripts/restartsrv_exim

Once completed, you can confirm the change is effective by viewing the Basic Exim configuration editor in WHM and looking for the Delivery behavior for suspended cPanel accounts option; It will reflect your newly selected behavior.
