The recent Exim update to version 4.97 has changed the length of the Exim message ID which means that MailScanner can no longer process them.

The symptoms are that MailScanner fails to process emails in the queue with errors in the logs stating that it cannot find the ID related spool file.

Our workaround has been to uninstall MailScanner to get the emails flowing again but obviously this has resulted in a massive increase in spam.

MailScanner were made aware of the issue on 06/11/2023 but to date there is no fix.
