8 Ways to Protect yourself from Forged/Fake Email

Monday, January 26th, 2015

The Internet is rife with fake and forged email.  Typically these are email messages that appear to be from a friend, relative, business acquaintance, or vendor that ask you to do something.  If you trust that the message is really from this person, you are much more likely to take whatever action is requested — often to your detriment.

Here we address some of the actions you can take to protect yourself from these attacks as best as possible.  We’ll present these in the order of increasing complexity / technical difficulty.

Split Domain Routing: Getting Email for Your Domain at Two Providers

Wednesday, February 20th, 2013

Split Domain Routing (SDR) is a term used to describe how users with email addresses in the same domain can receive emails at two different email service providers.

For example, let’s say the company domain is “my-doctors-on-call.com,” and you are moving your email from Email Service Provider X to LuxSci. You have doctors Joe and Emily, whose email addresses are joe@my-doctors-0n-call.com and emily@my-doctors-on-call.com. The migration is incomplete or needs to be migrated over time, so Joe still needs to get his email at Email Service Provider X, but Emily is all moved and needs to get her email at LuxSci. This is called “Split Domain Routing.”
