I developed a contact form on a client's website. When a user submits it, the client gets an email.
Is it considered as spam (or against best practices) when emails sent from a website form have
From: firstname.lastname@example.org header (with user's real address)?
The alternative is to have
From: email@example.com and a
Reply-to: firstname.lastname@example.org, which is also not perfect usability-wise (if the client uses an email client that doesn't understand reply-to), but I don't know if that is better given that the other option might get marked as spam.
