Event-driven architecture for accepting incoming messages

The SMTP Server component provides advanced set of events for message accepting and receiving, user authenticating and other operations.

All these events allow you to work with incoming emails in-memory and store manually to, e.g., database.

Using the SmtpFileHandler component you can automatically handle all these events and allow server to save emails to the disk like MDaemon, Communigate and other mail servers.

Relaying messages

With SMTP Server component you can easily decide which messages should be relayed and which should not. You can separate all incoming messages for your SMTP Server users from messages which should be relayed to recipients outside of your server.

By using of SmtpRelay component you can easily resolve mail exchanger for these recipients and relay emails sent to it.

Explicit and implicit SSL / TLS modes

Using SMTP Server component, you can specify how to start SSL negotiation protocol.

You can implicitly start SSL negotiation after the connection is established (usually, on port 465) or first connect in plaintext, and then explicitly start SSL negotiation through a protocol command - 'STARTTLS'.
