I'm getting hundreds of junk emails daily all advertising different companies but all emails start with email adress "contact-8155 (different No's on each email). see below for a few examples

Pimsleur  Learning (removed for privacy)
Cheap Auto Insurance (removed for privacy)
VA Loans (removed for privacy)


 how can I block these once and for all instead of having to block each individual email I recieve, There is no option to unsubscribe. There driving me mad? Please help
 I cannot block one header and get any others because each header and content is different - so I delete eachindividually each day and come back to a mountain of deletes if I go away

Junk emails are sending with my email address to my sender's email addresses.

The email contents are usually linked web address.

How can I provent this problem.

 

 

In one hour, I got 42 junk emails that had a little down-pointing blue arrow right before the unopened envelope.  Five other junk emails did not have the arrow.  This is the first time I've seen this.  Is it new?  Does it have some meaning I missed?  Thanks
