Special Notices
This section highlights the special notices that should be taken into consideration before upgrading your platform.
TFTP firmware install
Using TFTP via the serial console to install firmware during system boot time will erase all current FortiMail configurations and replace them with factory default settings.
Monitor settings for the web UI
To view all objects in the web UI properly, Fortinet recommends setting your monitor to a screen resolution of at least 1280 x 1024.
SSH connection
For security reasons, starting from 5.4.2 release, FortiMail stopped supporting SSH connections with plain-text password authentication. Instead, challenge/response should be used.
