Protecting against forged email

Lawyers are heavily reliant on emails, and often assume the authenticity of emails.

Unfortunately, emails can be easily forged, unless certain precautions are taken.

There are (simple) technologies to prevent, or reduce, such email forgeries, including SPF records, DKIM, and DMARC records.

Those records enable the recipient of an email to know how to verify if an email which claims to have come from your firm actually was authorised to come from your firm.

Without such records, your recipients cannot verify whether or not your communications have come from you, and they will not know to reject the forged emails.

Adoption of the above records is not widespread.

A good way to see whether your firm is publishing these records is to send an email to

This is risky because the signature may have been forged and/or placed on the document by an unauthorised person.  Conversely, it is open for an unscrupulous person to later claim that the signature was not applied by them or by someone else without their authority.

VPN Tunnelling through HTTP Proxy

I live at a college at University of Queensland, where we have pretty restrictive internet access. Data can be unrestricted, charged at 15c/MB (AUD), or through a HTTP Proxy at a much cheaper rate.

In order to get around this, I put my traffic through a HTTP proxy through a VPN to a remote host. Continue reading “VPN Tunnelling through HTTP Proxy”
