It is an active directory environment. But the problem is emails will be sent from devices such as printers, servers and web applications. They are normally not tied with user accounts and they can have different "from" addresses (we have multiple domains). > How do you expect to manage the login accounts of the users that are to > be authenticated?

As they are not in Active Directory, I am planning to create those in AD or maybe a MySQL server ( this is where I need help to decide) I am not sure how authentication is implemented for high traffic postfix servers. Just like when we use a SaaS solution like smtp2go, they provide us SMTP credentials which we can configure in the device or app to send email. _______________________________________________ Postfix-users mailing list -- postfix-users@postfix.org To unsubscribe send an email to postfix-users-le...@postfix.org
