Now-a-days, spoofing has become a very common technique in viruses adopted by spammers. There is no fool proof technique to avoid spammers spam the inbox with unwanted e-mails. In spoofing it is not necessary that the spammer is using your mail server to spoof your mailbox.

E-mail spoofing

The spammers sends a genuine e-mail to the user who is soon going to fall prey to spamming, this helps the attacker to ensure his/her existence over the web. If the mail does not bounce back that means the victims e-mail id is genuine.

The web user can fall prey to spoofing in the following ways:

Through a Virus : The virus takes the email address from an infected senders address book. It appears as if the email has come from a known user. This is the most common way of spoofing.

To stop such kind of spamming is to seek the infected users computer but it is virtually impossible.

Spam Spoofing : Some spammers send email and changing the return address to spoof someone else’s email account.

One thing to be noted is that the spammer here does not use the mail server, he just changes the reply to address in his email to spoof.
