New in SecureBridge: Support for the SMTP/SMTPS Protocols

November 13th, 2020

We are excited to announce the release of Devart SecureBridge with support for the SMTP and SMTPS protocols.

A new component — TScSMTPClient — was added to SecureBridge to support the Simple Mail Transfer Protocol (SMTP) and Simple Mail Transfer Protocol Secure (SMTPS). SMTP is the industry standard protocol for email sending — it allows the email client to send or forward messages to the receiving SMTP server. TScSMTPClient enables you to develop applications which primary purpose is to send email messages, or you can embed the email client functionality into an existing application.

The SMTP server is always listening for incoming connections. The client initiates a TCP connection to the SMTP server. After successfully establishing a connection, the client can start sending emails to the server. When you send an email, the SMTP server processes your email, decides which server to send the email to, and then relays it to that server.

We also supported Lazarus 2.0.10 and FPC 3.2.0 and added new methods and events to the TScFTPClient component:

  • the BeforeConnect, AfterConnect, BeforeDisconnect, and AfterDisconnect events;
  • the OnSendCommand and OnReadReply events for logging incoming and outgoing data;
  • the CEncoding and UseUTF8 properties for setting the encoding.

SecureBridge is a suite of client and server Delphi components which implement the SSH, SFTP, FTPS, HTTP/HTTPS, TLS/SSL, WebSocket/WebSocket Secure, and SignalR protocols. You are welcome to download and try out the new version:
