I have used the following code to send mail from my web application using a gmail account. My question is, can i change the sender address to another address other than original sender(gmail) address?
My code is as follows:
System.Net.Mail.MailMessage mail = new System.Net.Mail.MailMessage();
System.Net.NetworkCredential cred = new
mail.From = new System.Net.Mail.MailAddress("firstname.lastname@example.org");
Gmail doesn't allow you to change the FROM to something different than your gmail account.
It doesn't matter what you use, they over-write it, before they relay it on. This prevent spamming/spoofing.
