Today we released Nagios XI update 5.6.2 which improves a few features. The new Inbound E-Mail Processor now has the capability to accept HTML based messages. We also resolved an error message in the cleaner.log when using the Inbound E-Mail Processor. The Manage MIBs page has been optimized for Debian and Ubuntu along with the SNMP Trap interface. Scheduled FTP backups are now compatible with PHP versions less than 5.6.
