554 5.7.1 This message has been blocked because ASE reports it as spam.
I have extracted this info from Fortinet KB:
The AS Engine feature was released in FortiOS 4.0. A new AntiSpam Rule Set was also introduced in v4.0, this is the new rule which contains a Heuristic Antispam check for all suspicious spam upon passing through a firewall. READ MORE »
Just a quick reminder to myself, FortiClient SSL VPN can drop the dialing process if the “Mcafee security scan plus” is installed on the PC.
Check in “add/remove programs” if you see the “Mcafee security scan plus”, uninstall it and try to connect again.
A lot of security software like anti-viruses and personal firewalls can interfere with the dialing process of the SSL VPN, try to disable them if the problems persists.
Update:
Microsoft Security Essentials is blocking the dialing process too.
Update 2:
Try to disable IPV6 from network setting.

Beginning with version 4.0, Fortinet, for some reason, removed the PPTP VPN option from the GUI interface.
If the vpn was configured, prior to the firmware was updated to version 4.0+, the PPTP vpn server would have continued to function, without the option to make changes from the GUI.
In a freshly installed device or in a new device with a pre-installed firmware version greater than version 4.0, this option is disabled by default and for some reason, you need to enable this option.
The only way to do that, is to go to the CLI and enable it from there. READ MORE »
