Can Email be considered a document signed with a simple electronic signature?

Question

Email

When registering on the site freelansim.ru , and this is the site of the same TM, there is a strange clause in the rules.
13.5. When the Parties use e-mail, an electronic document sent with its help is considered signed by a simple electronic signature of the sender created using his e-mail address.
Doesn't this contradict anything, incl. common sense? :) After all, a simple electronic signature is a pair of login / password. And a simple e-mail, or rather a simple e-mail, by no means can meet this definition. Indeed, to send any letter, an smtp server is sufficient, such as sendmail, postfix, etc. Yes, there you can even just enter the telnet program on port 25. And when composing a letter, you can specify absolutely any return address, but at least [email protected] and no one will ask for any passwords. :) And since there is no password as such during the formation of the letter, so how can we consider that the email is a document signed by its return address as a PES and then equate it to paper documents signed with its own signature? :) Is there a violation of the law in the offer?

Answer 1

We can provide a return address, but the postal service will still store the address of the real sender. So an email, if it's not hacked, can serve as a signature. Although, a pair of login and password can also be hacked.

Answer 2

An electronic signature is not a username/password, but a pair of crypto keys. It cannot be hacked unless your private key is stolen.
