I have a site with some random users. Each user is able to set up a group. I want to set up a page where he can email his group members.
Question: I host my site on Godaddy.com. Can I allow the FROM: field to be the actual email of the user (e.g., he has a @yahoo.com email account)?
I have things set up so that I can send emails from my site to users. But right now, all the emails have email@example.com
as the sender (which is set up as a valid email account on host account), which goes through. Must the Sender always be a valid account on the email service being used?
I guess this makes sense for security (protect vs spamming reasons); otherwise, ppl can send mass emails and make it appear to come from legitimate emails (spoofing), right?
Anyways, I suspect this and wish to confirm. Thus, allowing me to understand what is and isn't allowed with email sending.
