The hostname configuration in mxGuard is expecting lowercase.


  1. Please update your IMail or SmarterMail configuration so that the official hostname is lowercase.
  2. Restart the mxGuard service.


 

Example:

Change uppercase and mixed case strings like these:

  • BIGMAILSERVER.CREATIVECLOUDSOLUTIONS.COM
  • BigMailServer.creativecloudsolutions.com

to a lowercase string like this:

  • bigmailserver.creativecloudsolutions.com
