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?
No you can't , even if you try, it will show to the receiver that it is a bad signature ( the message is being tempered ).
Actually you can copy the whole mail, along with signature, and send it to someone else. However, the signature will then be of the original sender, while the message will appear to come from you, so the recipient would know that some skulduggery is afoot.
Incidentally, Gaurav, signing messages with a key that is not available on the keyservers is useless.
