My website allows a person to enter their name and email address when sending out a referral. Then our site composes an email using mail() to send it out. But I think more and more ISPs are rejecting such emails because they think we are spoofing. The FROM: field on the emails going out use their name and their email address. What is the best way to overcome so much email being blocked?
- No longer attempt to use their name and email as the FROM?
- Have my site officially login to my STMP server and send once authenticated?
Can someone with experience in this area give me a suggestion?
