cPanel v11.46 and MailScanner

With the release of cPanel v11.46, changes in the cPanel provided Perl environment may cause problems with email delivery immediately following the upgrade. To resolve the problem all that should be required is a restart of MailScanner. This can be done either from within the WHM MailScanner UI or from the root shell with:

/etc/init.d/MailScanner restart

Check /var/log/maillog to ensure emails are processing afterwards. This should only occur on time after the initial upgrade into cPanel v11.46.

To pre-empt the issue, you could add the above command to /scripts/postupcp
