Assalamualaikum and Selamat Sejahtera
Today I would like to touch about Spam in e-mails. As an e-mails users, there are no doubts that everybody has been experienced when received Spams in their e-mails. For sure, these Spams is really frustrating to the users.
What is Spam?
Spam is defined as mass sending of unsolicited or unwanted message either to our e-mails or nowadays into our mobile phone. Normally, spam is using for spreading viruses, but there also spam for marketing and create publicity for products and services.
Therefore, spam will create less confidence to the e-mail users toward e-mail usage. By the way, for e-mail service provider, spam will increase their cost due to impose more storage, transmission and computing costs.
The only way to distinguish between legitimate message and spam is consent. If you asked for that information, it is not spam. For instance, an e-mail from friends is not spam.
There are several ways how the spammers get e-mail address. Firstly by using automatic programs or 'harvesters' to scan newsgroup, webpages and forwarded e-mails. Secondly by purchasing lists of e-mails from third parties and lastly by using 'dictionary attack' in order to try out all possible combinations of letters, common names and words in e-mail address.
Thanks you.
