The company where I work as IT Manager, have a SMTP Server from a provider, but it’s a only login and password to send mails from all allowed adressses We work with web application development, and the apps, devs and some services need to constantly sending mail messages

I was looking for some tool, like Gui managed to create accounts, and everything on to intermediate the mail sending

Like each application have his own login to send emails to this server Then it forward to the office/correct smtp
