|You can always check the ip address of any email that you receive, you just have to investigate the information in the header of the email, but the problem in case of spam emails is that this header information is mostly forged and is not of the legitimate source (sender). As said in the above post that spammers basically exploit the vulnerabilities of other systems for first making them into botnets and then and using these bots to send spam and phishing emails. So when the ip address or the sender will be traced back it will be some innocent guy who is completely unaware of enire thing that has happened from his machine. |
Practically no one can be 100 protected from spam, most of the spam emails are generally blocked by the spam filters employed by email providers but still pass through as spammers invent new techniques every day.
The best way to reduce spam is to report about it to your email provider if you are receiving same type of spam emails again and again and then they will check and investigate the email, trace it out and appropriately modify their spam filters based on the frequency of spam emails of same type.
