I am building an application using Ruby on Rails. I want to do something that I am not even sure is possible;

I have a mailer that is working, however I want to enable users to send emails using their own email address in the FROM parameter. Its almost as if the “:from” parameter has no effect on the email sent.

I’m a bit of a noob when dealing with email servers so please be as detailed as possible. I doubt there is a smtp mail server set up on my hosting account, so if I need to do something like install smtp on my hosting account please be as descriptive as possible.

    You are able to set the From: field to whatever you want, theoretically, but in practice you are often limited as to what you can put in there. Many email providers will automatically replace the From address with your own regardless so that you can’t masquerade as someone else.

    You’re probably intending to do something like this:

    From: Example Customer Name <name@example.com>

    Also keep in mind that sending email from arbitrary domains will result in a very high chance of being flagged as spam since you are most likely not listed as as a host authorized to send for those domains which is typically implemented with SPF.

    The best practice is to set the address to be something like this:

    From: Example Customer Name <you@yourdomain.name>

    That way you’re not spoofing your actual email address, only the associated label, which is not typically verified.
