Warning: Exim v4.97 breaks MailScanner

An update that was made to exim v4.97 has broken the functionality of MailScanner. The update has made the exim Message ID a different length which MailScanner cannot process.

Currently, this issue does not affect cPanel, but does affect DirectAdmin if exim is upgraded to this version. 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.

We have released a modification to MailScanner that addresses this issue:
