ExEMail is a lightweight, 100% ATL-based ActiveX component that enables applications to send fully compliant SMTP email messages, including binary attachments (MIME) and HTML-formatted content. It can be easily integrated into any development environment that supports ActiveX controls.

What Sets ExEMail Apart from Other SMTP Components?

• Built-In DNS Lookup for SMTP Server
  ExEMail can automatically determine the appropriate SMTP server for the recipient's domain by querying a DNS server, eliminating the need for hard-coded SMTP settings.
• Non-Blocking Message Delivery
  Unlike many other components, ExEMail sends messages asynchronously, ensuring that your application remains responsive during email transmission.
• Event-Driven Feedback
  A comprehensive set of events provides real-time feedback on the delivery process, making it easy to track progress or handle errors.
• Rich and Intuitive Object Model
  Designed to be flexible and developer-friendly, the object model simplifies integration and customization.

How ExEMail Delivers a Message

1. DNS Lookup
   ExEMail queries a DNS server to find the SMTP hosts responsible for the recipient's domain.
2. SMTP Server Connection
   It attempts to connect to each SMTP host returned by the DNS query, in priority order.
3. Recipient Negotiation
   Once connected, the component communicates the sender and recipient email addresses to the SMTP server.
4. Message Transmission
   If the server accepts the addresses, ExEMail prepares the message - including headers, body, and attachments - and sends the data.
5. Connection Termination
   After successful transmission, ExEMail gracefully closes the session by issuing the SMTP QUIT command and disconnecting.
