comment How can I tell if a PPTP tunnel is secure?
User has the ability to check the security methods used in the connection. As an example, by opening the dial in properties and going to the Security Tab (Windows). Data Encryption should be "Maximum strength encryption(disconnect if server declines)". Authentication should be EAP-TLS, PEAP or Smart Cards. MSChapv2 is absolutely not recommended (least secure). Certificate based security it recommended. In order to check whether the DNS requests are secure, he/she can use online tools such as GRC. FYI: PPTP is not secure at all. Its outdated and can be cracked using nthash.

comment Emails wrongly flagged as spam by filter, claiming suspicious URLs
Its not outlook. However, it has options to block Japanese and other content. But no such tag attached. And this error specifically say that it is a URL which is not trusted. It is also possible to examine the complete header to check for the specific endpoints (except client endpoints). By examining it is possible to find out which service and integrated systems have caused this. If not, this is an end point product (client software).

comment Emails wrongly flagged as spam by filter, claiming suspicious URLs
My point is that there are possibilities. This does not happen without a reason. This specific message indicates that this was due to shortened URLs. However, what I mentioned was about the forwarding (mail flow) path. There could be 2 forms of filters who do this. One is a server side product (i.e. Forefront/Barracuda) or a client Anti Virus solution. If the emails sent to Japan, there is a good possibility that Sourcenext products marking these as spam. However, this can be mitigated (by the end user). Avast and other client security software could do a similar thing (configurable).

If that is the issue, you need to contact the specific users and work with them to identify possibilities. However, by checking the headers, it is possible to identify the forwarding servers. Thank you!
