I am just curious to know the advantage of using the PGP signature. Does it authenticate you better or result in no bouncing or rejection of mails by spam guards? Suppose I copy and paste the text in a fake email like the one below, I will appear to have the same authentic signature. So what is the safety or advantage?
that signature is created using the senders private key and the msg so it will be diffrent for diffrent msgs.

the reciver has the senders public key (from some key server or so). to the recivier the msg and the sig will not match and hence infer that the sender is being impersonated or the msg was tampered with in transit.
