Is it possible to send email using the SMTP server of my subscriber’s website host? Customers who register at my site should be able send email by using my web app. I would like to use their SMTP server to send any emails that my customers want to send to their clients. I don’t know what the relay problem is, that’s why I want to confirm. TIA.
Thank you for the clarification. That was my original assumption. Now I can test it to make sure that I don't run into any other problems.
