Turnpike Security
- Turnpike lets you set up a large number of users on your LAN, if you wish, and routes email to whomever it is addressed, keeping it secure from other LAN users.
- Turnpike security is very tight as email is encrypted in the database, and the software deliberately handles a very small subset of HTML. You get warned if you try to use Turnpike to run a suspect attachment - you can still do it of course, if you trust the source.
- We continue to have no reports of any virus targeting Turnpike.
- Turnpike is highly standards compliant and follows the RFCs. Turnpike Six has a very high GNKSA rating too (More about Good Net-Keeping Seal of Approval).
- Use Turnpike with third party PGP software to encrypt and sign your email. You can also distribute your public PGP key free of charge via the Demon key server at http://www.pgp.uk.demon.net/
- In September 2004 a security flaw was announced in a Microsoft DLL that handles Joint Photographic Experts Group (JPEG) images. Turnpike does not use Microsoft's JPEG viewer, but sometimes the malicious images caused earlier versions of Turnpike to immediately shut down or crash. Although it does not seem that the specific Microsoft-targeted exploit works (there's no virus infection or insecurity left behind), as a precaution Turnpike 6.04 onwards gives the user a warning of suspect JPEG files in email or when reading newsgroups. Turnpike does give the user the option of launching another program to view images by clicking on the "viewer" button. In this case we have no control or say in what third party software is run.
