Spam disguised as spam notification

In their constant battle against anti-spam filters, spammers have recently started to camouflage their messages as spam quarantine notifications:

Looks quite legitimate, don’t you think? The spammers are obviously counting on the recipient’s curiosity – the message says to ignore the message if the user thinks it’s spam, or to click on the link to check out the message. According to TrendMicro, the site to where the link leads has been already taken down, but let this serve as a warning for next time.

How to be sure that the message is, in fact, spam? In this instance, a closer look at the address from which the email is sent will show the discrepancy. The sender is purportedly a security company, but the sender’s domain name is indosatm2.com, and it belongs to an Indonesian Internet and multimedia services company.
