Why anti-spam?

Why anti-spam?

Sending emails and receiving emails are part and parcel of our daily routine. Due to my work’s nature, I received a few hundred emails a day. Mostly, these are notifications. However, they can be warnings if something went wrong.

To me, these are relatively important emails. However, I’m receiving unwanted emails or known as spam emails every day. Honestly, they can be from anywhere even you may have not corresponded with them before. Your email address can be known in several ways; harvesting, your recipient’s computers are infected by backdoors, you have enrolled to some events, your email address was sold to someone etc. Basically, they are not within your control.

I’ve personally tried, receiving emails without anti-spam. GOSH! More than 50% of the received emails were spam emails. I quickly switched back on my anti-spam gateways. I’m getting near to zero spam email.

With the anti-spam, it is a big relief. Without it, I have spent a few hours to remove those spam emails. A few hours, maybe  2~3 if you add them up. I was thinking, I can have a good rest for that 2~3 hours, why do I’m stupid to turn off the anti-spam filtering? Actually, it was my curiosity about my new anti-spam gateways.

So, it is clear that I need anti-spam for my mail server, Do you?

Anti-Spam Saga

Anti-Spam Saga

It is all about anti-spam. Many have the wrong impression or little understanding of anti-spam. Even a lot of IT admins have a faint idea on anti-spam.

Emailing is more like a daily routine for many. Ask yourselves on how much do you understand on anti-spam. Most will tell you spam emails are those unwanted emails. But how?

Hopefully, I can make this understanding better. When someone told you I’m receiving a lot of spam emails each day, there are a few things to ask and examine. How do you determine those are spam emails? Where did these emails go to? If the subject has ‘SPAM’ classification? What kind of anti-spam solution do you have?

Anti-Spam has become very complicated. Especially those have installed anti-virus application on their computer has an anti-spam function too. The double filtering creates a lot of guessing games. We have cases whereby the email was quarantined by the local computer without users noticing it. However, the users plastered the server admin on such event.

Honestly, there are a few ways to determine a spam email. These rules are predefined and read by machines. The most common method is to use realtime blackhole list known as DNSBL The lists are maintained by various spam agencies,. Control panels and mail servers etc use these list provided free to reject or define spam emails.

Yes, it is common but less effective against spam emails. The more effective methods are combining a few like detecting spammy words, the type of charset, trusted senders and training the anti-spam system on the types of emails you wanted to receive. A good anti-spam system allows you to quarantine, reject or inject the spam classification into the subject that these emails have classified as a spam email.

You may have the best anti-spam system but I realized there are organizations have many false-positives a lot of tuning from time to time. The sender can be a newcomer, his or her email was rejected because it has violated the anti-spam rules even it was genuine. I have found the courier and logistics companies cannot have very stringent anti-spam rules and you need to check the process often to avoid unnecessary delays.

I want to say you need a good mail server admin to minimise the hiccups even you have a good anti-spam system. When this has happened, he or she is able to check from the header and do the necessary adjustments in quicker turnaround.

How to reduce spam emails?

Actually, it is frustrating if you are receiving a lot of spam email. Even you have so-called the best anti-spam on your email service, you can receiving spam email, maybe lesser and at the same time, you might treat some emails as spam email, known as false positive.

As far as I’m concerned, there isn’t 100%. With anti-spam you are receiving lesser definitely but your definition is never the same as the server. Some anti-spam require you to set rules or train them in order to be effective

Thus, you cannot eliminate those spam emails defined by you. However, you can still minimise receiving spam emails without spending a lot to or buy a good anti-spam. Here are a few tips to help you;

a. Never use your ‘work’ email to do registration online for personal use, Your email address can be sold to someone for bulk sending. Always think twice if registration is necessary.

b. Avoid common account name like help, sales, enquiry or similar. If your name is John, avoid using john@, and add your last name.

c. Do not advertise your email address. Spammers like to use harvesting technique to collect email addresses. Common areas like auction portals, buy & sell portal etc.

e. Make sure you use SPF in your domain name DNS allows only permitted email server to send email on your behalf. I recommend ‘-a’ at the end of SPF record if you want to enforce those emails impersonate your organization.

f. Use effective RBLs on your email server. Reputable RBLs filter emails sent from bad IP addresses.
