Problems with Email Spam.


Email spam has steadily grown since the early 1990s.  It has grown over time and has created a strong negative reaction in many Internet users.  I think everyone is annoyed by the massive loads of email spam that continuously gets slammed into our inboxes.  It has been a nuisance and has gotten even worse over the last several years.  It seems like the volume of email spam has doubled in the last month.

Spam emails are the most widely used method of fraud. Spammers send varied types of fraudulent emails.  For the uninitiated, unsolicited marketing emails are considered spam.  One way to deal with spam or unsolicited emails is thru email filters or email filtering spam.  Spam emails are sent that include links to banks or other organizations that appear legitimate.  Spam emails are estimated to cost anywhere between US$10 to $87 billion per year in direct costs and lost productivity.

The estimated losses that can occur because of spam emails are lost productivity and loss of important information.  Spam emails are those you receive in your inbox appearing as a mass email for a certain product or service.  Now I receive only the emails that come from random, one-use, email adresses.  Writing the subject lines for your emails can be one of the most stressful steps of  email marketing .  It would be hard to find anybody that would claim that those marketing emails are not perfectly legitimate.

Sometimes, however, even those important emails may find themselves sitting along with spam mail in the junk mailbox.  The emails weren’t bouncing back and they weren’t appearing in the junk mail folder.  Our mail server was reporting that the emails were being delivered, however we couldn’t see them in our Hotmail account.  The reason Hotmail has received better spam reviews is they block emails that they deem unworthy of user's attention.  They have experienced a drastic reduction in SPAM emails that target the business, thus allowing them to maintain their security.

However, some emails that are work-related end up being spam as well.  As part of the Exchange 2010 upgrade,    spam emails will no longer be marked with this tag.  This is a very precious info for Computer users as 95% of all Emails is Spam.  As you can see, your emails can get flagged as spam, even if you're not a spammer.  Images in emails can be adapted to send messages back to the spammer.

For example, of Oregon's 2.5 million voters, only 20,000 emails are in the state's database.  They are also often used to access absentee ballots for overseas and military voting.  Not all of your emails are making it to your intended recipients.  What matters more is the latter--the number of emails that reach the intended recipients' inboxes.  It is not necessary that encrypted emails are safe from hackers.

They return the emails that top a certain score before they are even sent to the receiver.  Another problem that can occur with emails is that there cannot be any certainty that has sent the message.  These emails are wrongly assumed to be the cause of a server problem that is not operating effectively.  The primary motivation behind these emails is identity theft.  Spam can be more than an annoyance - unwanted emails can contain viruses or phishing scams.

They link that are contained in such spam emails may contain some dangerous viruses.  It doesn't matter that other recipients think your emails are more valuable than their own spouse.

The throwaway email address is tied to a real email address.  A protected email address is safer to put on a web page.  If your email address is in your email signature, you can eliminate it or us the same technique.  This only tells the spammer the email address is valid and will increase your spam email.  The spammers email address might include the ISP's name. 

In the simple example above, the from name and email address was added as the fourth parameter.  So, by using this JavaScript code, the email address isn’t technically part of the text portion of the webpage.  Obfuscating your email address is all well but it doesn't really help with the accessability of your site.  Once your email address has been compromise, all you can do it attempt to filter it.  Some people are not aware that their electronic mail address has been harvested by junk mailers. 

The methods of spammers are likewise costly.  These email spammers are breaking the federal spam law, The CAN-SPAM Act of 2003, in every way possible.  When people stop using email, then spammers will stop sending spam through email.  They are contracted by real companies to send mass email.  Sometimes spammers will try lists of common names or words in different combinations to locate an active email address.

The bane of inboxes everywhere, spammers are daily exposing your recipients to  phishing scams  and other nasty pursuits.  They may engage in deliberate  fraud  to send out their messages.  Since e-mail is so cheap to send, a tiny number of spammers can saturate the Internet with junk mail.  Remember that spammers are constantly refining their social engineering tactics.  Many spammers are very crafty in their techniques and are difficult to trace.

Basically email filtering is a process which acts as a shield to inbound and even existing emails.  Content filtering hasn't been a big component of spam filtering algorithms for nearly a decade.  Regardless of how good spam filtering has become, false positives will always be a problem.  And for the right reasons, subject-line filtering is too easy to trick and that is exactly why it isn’t effective.  This form of content filtering is much harder to disguise as the URLs must resolve to a valid domain name.
