sending emails from addresses i don't own

[dadamssg87]

I've noticed you can send emails with PHP coming from any email address. So it seems like i could spam a ton of people with email addresses with "donaldtrump@trump.com" or something like that. I understand emails are trackable so i'm sure i would get in trouble if i spammed enough people.

 

I was wondering though if theres any issue with sending emails for your app users? For example, say i come up with a service to design and send emails. My user would customize a template and enter some text and then enter the email address they want to send from and the email addresses they want the email sent to. So pretty much like mailchimp.

 

Would i run into any problems with sending emails "from" email addresses i don't own, technically or legally?

The "from" is just a header and doesn't mean much. You can still see where the email actually came from.

 

With that said, I don't think you should make the "from" another user's email address. Maybe make the reply-to their email address. Make the from something like "no-reply@domain" or something.

This is the nature of email-- all the fields can be spoofed.  With that said, spoofing the from address will earn you points against from spam detection engines, and may cause you to end up on an RBL.  It also is the type of feature that can be exploited by spammers.
