This is a rather complex feature that deserves a specific coverage just for itself. SMTP Chaining allows you to:
- Build a distributed MailNow! system. This caters for companies that need to have multiple MailNow! in multiple offices. Using this feature, all the different offices can host the mailboxes for their local users yet still share the same corporate domain. This is made possible by SMTP Chaining which effectively connects all the MailNow! server together to act as one single distributed system.
- Spread the load of your email server across multiple system. If you have a many users in your company, you might want to segregate them into multiple servers to ensure better reliability and speed.
