I making one application that can send different email, but the email address depends of the user. I'm using mailjet to do this, after reading the doc, it's seem that i have to add every email for have the right to send email from this address, but this address are not generate by me (they are gmail, toto, etc)
I already use the Java API of mailjet to add user, and this part is working fine
But my problem is when the validation email arrive, and the person follow the link, mailjet ask to login, but he do not know what to do, because normally is my own account, i only what to add their email address to have the right to send email with them.
So the question, is how i can add email address (from gmail, yahoo...) and activate the user, without the login part.
