What should you do? Learn to Identify Spam Emails.
Here Are 2 Quick Steps You Can Take:
Step 1 – Find the sender’s real address.
You can see that the sender’s address is from “365 Mailbox”, which implies that it’s from Microsoft Office 365. However, if you look closer at the “From” address you’ll see that it’s actually coming from someone at “fyndeverything.com”. This is your first warning that it might not be from Microsoft.
Step 2: Check where the link in the email actually points.
Don’t click the link, but hover your pointer over it. This will tell you where the link actually goes. In this case, it would take you to “ief.com” and not a Microsoft address. So, you can see that this message is definitely spam.
Here’s another example of a spam email. You can see that this email is not from Dropbox, but from “sharing.dboxfile.com”. Plus, the “Download” link isn’t from Dropbox. Instead, it would take you to “gpmotoscaminas.com.br”.
Why are you getting spam emails in the first place?
95% of all the junk mail you get is probably because you gave your email address to somebody who leaked it to a spammer. Some businesses will also sell your email address to other companies.
You may be getting spam because you sent mail to someone who wasn’t connected to your local server. This slows down your email and gives spammers free bandwidth to get in.
Spammers also use something called Trojans/Script capturing by using HTML emails to confirm your email address. The best way to disable this is to go to the preview window and delete the message. You can also disable HTML emails.
Another way spammers can get your email address is through Dictionary Attacks. This is when spammers connect to your server and try random addresses to get through. They do this by going through the alphabet. Make sure your server blocks the sending server after a number of failures. You can also set it for a maximum number of recipients per message, or set a delay between recipient addresses to slow the spammer down and get them to go elsewhere.
