Since this morning, I have received on my professional address
firstname.lastname@example.org (that usually receives very few emails, between 3 and 5 a days) three strange messages:
sender: ***@yahoo.com subject: test content: Sent from Yahoo Mail!
sender: ***@yahoo.in subject: None content: Verifications 16316 6 16 1 11 1
sender: ***@outlook.com subject: Verification-2109GEds145 content: Verification Purpose only sdfsdf4 d
I am guessing that my professional address has somehow gotten in the cloud, but what is the purpose of these repeating emails that I receive? Is it spaming stage 1, where senders are veryfying that my email address is not bouncing?
How can I:
know the purpose of these emails - are they just spam or is it something I should be more scared about?
try to prevent or correct my receiving of such emails?
PS : the X-Original-To and Delivered-To addresses are email@example.com, but i see no address in the "To" field that displays in my email client
