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.

These are forms of social engineering — the “bad guys” trying to establish a trusted context so that you will give them information or perform actions that you otherwise would not or should not do.

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.

7 Common Misconceptions about DKIM in the Fight Against SPAM

Monday, August 18th, 2014

The popularity and prevalence of DKIM in the fight against SPAM is growing such that as of August, 2014, 47% of the most popular domains in the USA are DKIM-enabled (reference); globally, that number is 38%.  The trend is steadily upward and we expect DKIM use to be pervasive within a few more years.

DKIM, Domain Keys Identified Mail, is still a magic techno-jargon black box to most people. It’s “something” you gotta “add to DNS” to help stop SPAM or make your email “appear more legitimate”.  Beyond that (and even what DNS actually is) … many people are stumbling to know what is going on.

Here are 7 misconceptions about DKIM that we have seen, and the explanations that can steer you back on  track:

1. DKIM stops SPAM

Many folks believe that enabling DKIM for their domain and DKIM filtering for their inbound email will stop SPAM from reaching them.  Certainly using DKIM filtering on your inbound email will cut down on SPAM and using DKIM for messages sent by you can help others verify your email is legitimate; however, it does not actually stop spam.  In fact, it can make some SPAM look more legitimate.
