our company are lunching a new website mycompany.com and the web hosting vendor ask we to setup something like noreply@mycompany.com, so they can send out new feeds, notifications, confirmation, password reset info, to the website users.
The vendor mentioned if we have the email account set up to allow SMTP sending of emails, and they will handle the emails on their end.
do we need to setup SMTP relay in this case? is there a better solution?
we can either use their IP for the replay or use user authentication?
