Does the digital electronic signature convey the sender's address in the ip letter? Send via Outlook

Answer 1

The sender's IP address is written in the headers of the letter by the mail server that receives the letter from you, and all subsequent servers in the transmission chain supplement the information
(I have never heard about the IP address in the EDS, but I can not guarantee the absence)
