How to clear the Exim retry database

Introduction

After fixing an issue that caused Exim to defer sending messages with "retry time not reached for any host" as the reason, Exim will continue to defer messages. The retry database, also known as the hints database, must be cleared to send messages again.

Procedure

1. Access the server's command line as the 'root' user via SSH or "Terminal" in WHM.
2. Run the following commands:

   /usr/local/cpanel/scripts/exim_tidydb

   mv -vi /var/spool/exim/db/retry{,.$(date +%s)}

   mv -vi /var/spool/exim/db/retry.lockfile{,.$(date +%s)}

3. Restart Exim:

   /scripts/restartsrv_exim
