People I don’t know say they are receiving SPAM mails from my email address
It is a well known problem through years.
It is properly not coming from you, but your email address can have been picked up somewhere public like a message board or hacked from a company where you have once registered.
There is little you can do and it will soon blow over again. Make sure that your have your Anti-virus installed and updated!

My customers and contacts are receiving SPAM from my email address
This is also a well known problem. This is a little worse, but it may not be your computer. One in your network of contacts may have had a virus that send them the whole contact list and now you are on it. For a while, you will properly see emails sent to or from you along with people you know. Make sure you have your Anti-Virus installed and updated

If you are in a company and you have network of computers and suspect that SPAM are being sent from in-house, please check the following below:
If you have double checked your own Anti-Spam product on your server and eliminated that possibility, please see the below tips that will properly solve your issue.

Configure your firewall
Ensure that only authorized users can send emails via your internal network. This is accomplished by creating a rule in your firewall to drop all outbound traffic on TCP port 25 (SMTP).

If you are hosting your mail server inside your internal network, ensure that you make an exception to the above rule to ensure that the mail server can still deliver on your behalf.

It is advisable to log dropped packets, so that you can identify any rogue computers on the network attempting to deliver mails directly.

Enable SMTP Authentication
Now that emails can only be delivered through your mail server, you must ensure that it will only rely emails on behalf of authenticated users.

Failure to do so will leave you exposed to abuse of the server, so it is important to get the configuration of the mail server right.

Protect your domain
Let everybody know who are trusted sender of emails for your domain. This can be accomplished using Sender Policy Framework (SPF):

You should create a SPF record stating that your mail server (and possibly any 3rd parties) are the only trusted senders for your domain.

Don’t hesitate to call us if you have any questions about Anti-Spam or Anti-Virus products for your Business or Personal clients.

Train yourself to use strong passwords


With the uptick in cybercrime in recent years, it is critical that we don’t lose sight of the simplest precaution we must take to protect ourselves – using strong passwords. We might think it’ll never happen to us, but the latest security breach at LinkedIn is a reminder that a strong password is our last line of defense when it comes to protecting our personal information from hackers.

A strong password is one that’s difficult to guess by humans and computers, is at least 6 characters, preferably more, and is a combination of upper- and lower-case letters, numbers and symbols.

Experts also recommend that you:

  • Don’t use common passwords that are easy to crack like “12345”, “abc123” and “password.”
  • Use the full keyboard including letters, numbers and special characters in seemingly random sequence, not in the order they appear on the keyboard, like “1q2w3e”.
  • Don’t use any words from the dictionary. Also avoid proper nouns or foreign words.
  • Don’t use anything remotely related to your name, nickname, family members or pets.
  • Don’t use any numbers someone could guess by looking at your mail like phone numbers and street numbers.
  • Don’t reuse your last 15 passwords, and change them every 90 days.

Right, you say. I’m lucky I remember which password goes with which account! (You aren’t using the same password for all of your accounts, are you?) Luckily, there are ways to make remembering strong passwords easy:

  • Use phonetic spellings of words and substitute some letters for numbers or characters that resemble them. For example, replace “t” with “+,” “s” with “$”, and “p” with “9”.
  • Choose a phrase that means something to you, take the first letters of each word and convert some into numbers and characters.
  • Use an adaptable base password: a base password combined with additional characters depending on the context. For example, take the first letters of each word of your favorite quote and add every consonant in a brief description of what the password is used for, like “2bon2bbnkccnt.”

These strategies can be combined to make for some pretty strong passwords that are difficult to crack, even for a computer program.

If you really want to get serious about strong passwords you can use Diceware. Basically, Diceware is a method for choosing passphrases that uses the results of five dice rolls per word in your passphrase. The resulting numbers are matched to random words in the Diceware Word List. You then combine the random words to make your passphrase. The site recommends choosing between five and seven words for your passphrase.

If the latest high profile security breaches have you thinking you need to come up with better passwords before your accounts get hacked, use these guidelines to get started today. While it may seem like overkill, you’ll be thanking your lucky stars the day your favorite social network – or worse, your credit card company – gets hacked.
