Regular Smtp ServerThe built-in Smtp server is the default mechanism in Xeams to accept new messages from a client. This Smtp Server accepts in-coming emails and stores the message in a local repository. If the message is bound for another SMTP server, the message gets queued and is finally delivered to the destination. If you decide to use Smtp authentication, you will have to create local users in Xeams.
This Server can be used in all 3 operating modes (Stand-alone, Spam Firewall and Hybrid) of Xeams

The regular SMTP server can be used in all 3 modes (Stand-alone, Firewall as well as Hybrid)
Smtp Proxy ServerThe built-in Smtp Proxy server can only be used if you have another server in your network that accepts emails. It sits in between a client and this other Smtp server. It does not have a local queue. Instead, when a client connects to send an email, the proxy server opens a TCP/IP connection to the actual server and simply watches what the client is sending. Besides watching the email, it can also modify and block the message. If the actual server goes down, so will Xeams. A proxy server requires less configuration in Xeams. You do not have to configure domain names and users in Xeams. This is because the primary server decides which emails to accept.
This Server cannot be used in Stand-alone mode. It can only be used in Spam Firewall and Hybrid modes.
When should you use Smtp Proxy Server?Consider using Smtp Proxy Server when:
The SMTP proxy server cannot be used in Stand-alone mode.
