Supports MIME and S/MIME

When designing the IMAP component, we mainly forcus on ease-of-use, performance, reliability, and flexibility. As a benefit, you do not need to have deep knowledge of how the IMAP protocol is implemented and how to read, encrypt, decrypt, sign and validate a message. IMAP component does all the hard works for you. The following is a list of some key MIME and S/MIME features:

• Load and save message from/into MailMessage object
• Supports multiple recipients with To, CC, and BCC headers
• Attach multiple files
• Encrypt, decrypt, sign, and validate email messages easily
• Extract attachments from MS-TNEF (winmail.dat) files
• Import HTML file or web page into e-mail
• Forward message as attachment
• Base64 and Quoted-Printable
• Fullly support creating and displaying HTML messages with embedded resources such as Image, source, etc. in your applications

Security and Reliability

The Ultimate Mail component provides industry standard security using the Secure Sockets Layer (SSL) and Transport Layer Security (TLS) protocols. Our components support strong, commercial grade encryption, and we do not rely on any third-party toolkits which have licensing restrictions or are encumbered by patents. By setting a single property or option, the component automatically handles all of the complex certificate management, protocol negotiation and encryption for you. Even advanced options, such as using client certificates, are handled easily with just a few lines of code.

Supports HTTP Connect, SOCKS4, SOCKS4A & SOCKS5 Proxy Servers

Ultimate Mail provides full support for Proxy Servers such as HTTP CONNECT, SOCKS4, SOCKS4A, and SOCKS5. By simply setting a few properties, you are able to download, upload, send, and manage email messages and mailboxes from POP3, IMAP, and SMTP servers through the desired proxy server, providing your application with the greatest flexibility and highest level of security available.

Support for IPv6, the next generation Internet protocol

IPv6 (Internet Protocol version 6), the next-generation protocol designed by the IETF (Internet Engineering Task Force), will gradually replace the current version of the Internet Protocol, IPv4.

With Ultimate Mail Component, users have an integrated service assurance solution that will provide them with Mail, and Proxy capabilities in mixed IPv4 and IPv6 environments. This helps organizations with the adoption of and the transition to IPv6 by making the management of such networks seamless.

.NET Technology

By using 100% managed code written in C#, the Ultimate Mail component takes advantage of the numerous built-in features of the .NET Framework to enhance performance, moreover, the component is CLS compliant, and it does not use any unsafe blocks for minimal permission requirements. In addition, the component is highly compatible with Microsoft ClickOnce.

Supports many .NET Platforms

Ultimate Mail Component for .NET supports the following platforms:

• Windows Forms
• Web Forms
• Web Services
• WPF

Ultimate Mail is fully compatible with Visual Studio 2005 to 2013 (.NET 2.0 to .NET 4.5.1). As a benefit, you are always up-to-date with Microsoft's Technologies when using our products.

Supports event-driven (Asynchronous) and blocking (Synchronous) Design

Most applications written with the Mail component will be synchronous. Synchronous method gives you the ease-of-use, but it can only returns the control back to the caller after it has finished, meaning that it blocks the execution of the caller for a period of time. Using synchronous method is recommended when you only need to execute one Mail operation at a time.

You might decide that your design requires an asynchronous operation when it is needed to manage email messages simultaneously. Asynchronous methods provide a great deal of power. Asynchronous method is executed on a thread separate from the calling thread. Such operation is useful when an Mail operation is time consuming and other codes need to execute without waiting for the initial operation to complete. In addition, the user interface will be most responsive when asynchronous methods are used.

Flexibility

The Mail component has been designed with a great degree of flexibility and can be used with a wide variety of programming languages and different types of development environments. Available as a managed .NET class, it is fully supported by languages such as Visual Basic, Visual C#, J#, Managed C++, Borland C# Builder, and Delphi.

Fully Documented

As important as functionality, features and stability are, comprehensive documentation is equally as important to the application developer. This is why the ComponentPro Mail for .NET product includes a Developer's Guide and a complete Technical Reference which documents every property, method and event supported by the component. A printable version of the documentation is included with the product, as well as context-sensitive online help which can be accessed directly from within the development environment.

Lots of complete Mail client samples in C#, VB.NET, and ASP.NET

In addition to the fully documented Developer's Guide and a complete Technical Reference, Ultimate Mail component also includes a number of samples with full source code which help you become familiar with the features of the component and provide code which you can re-use in your own applications. The setup package contains three complete Mail client applications: Mail Console Client, Mail WinForms Client, and Mail WebForms Client.
