Rule (technique) to delete unusual spam e-mails

[smfcpacfp]

In my inbox I see the following address <https://lnkd.in/???????> for spam e-mails with various combinations of letter and numbers where the question marks are. When I click on the message to look at it to create a rule I see something like this as the sender’s address:

Skin Tag al@19bob.website pp2

Obviously this is a scam technique to avoid deleting e-mails from <https://lnkd.in/???????>, the real source of the spam. Can anyone tell me a way to delete e-mails for the real source of these e-mails?
