IP by email how to find out?

Question

Email

Letter mailing unconfirmed Email

Answer 1

Theoretically, this is possible, but the complexity is comparable to determining the number of a car from its tire marks. That is, there are options, but you will not do it on your own. You will reach the maximum ip of the mail server, but what will it give you? Or even further, get an ip address that is used by 5000 people from some city. What's next? Why do you need ip?

Answer 2

No way.
Vasya Pupkin bought a VDS in Pindosia, from which he enters via VPN somewhere in the Galapagos Islands and from there launches a spam mailing list. Well, you will recognize the IP of the server from the Galapagos Islands - you can see it in the header of the letter, as well as in the logs, if the server is yours - so what? These islands belong to the state of Ecuador - will you go to the Ecuadorian embassy?
And even if Vasya turned out to be fantastically stupid and sent spam from his own computer - well, you will find out the IP of the city of Zapindyurinsk, through whose NAT half of this city goes - then what? The provider will not show you the logs, only at the request of the court (well, or by a very good acquaintance).
Why waste so much time on spam? Pressing Del takes much less time

Answer 3

Prove nothing... Relax.

Answer 4

You can see the source of the mailing in the headers.
