The Chilkat .NET Email Component is a commercial software library used by developers to create, send, receive, and manage emails within .NET applications. It functions primarily via two essential classes: Chilkat.Email (to construct the message payload) and Chilkat.MailMan (to manage the server connection and mail transport). Core Features

Protocol Support: Fully handles SMTP for sending emails, as well as POP3 and IMAP for retrieving them.

Security & Encryption: Supports SSL/TLS connections, STARTTLS, SSH port tunneling, and advanced S/MIME formatting for signing or encrypting messages.

Automatic Parsing: Handles complex MIME formatting, charsets (like UTF-8), and encodings automatically.

Media Handling: Separates distinct email elements into proper file attachments or “Related Items” (like embedded HTML images and CSS). Step-by-Step Integration Guide 1. Installation

To include the library in your project, install the cross-platform package from NuGet. For modern .NET Core, .NET 5, 6, 7, or 8+ applications, use the Chilkat NuGet Package Manager: dotnet add package ChilkatDnCore Use code with caution. 2. Component Initialization & Unlocking

Because Chilkat is a commercial product, you must initialize the library by passing an unlock code globally before utilizing any components.

Chilkat.Global glob = new Chilkat.Global(); bool success = glob.UnlockComponent(“Your_30_Day_Trial_Or_Purchased_Key”); if (!success) { Console.WriteLine(glob.LastErrorText); } Use code with caution. 3. Sending an Email (SMTP)

To transmit a message, configure the MailMan object with your mail server’s credentials and link it to an Email object.

Hello!

This is an HTML email.

”); email.From = “Sender Name [email protected]”; email.AddTo(“Recipient”, “[email protected]”); // 3. Add an Attachment (Optional) email.AddFileAttachment(“C:\documents\report.pdf”); // 4. Send the Email bool sendSuccess = mailman.SendEmail(email); if (!sendSuccess) { // Chilkat records rich execution history on failures Console.WriteLine(mailman.LastErrorText); } Use code with caution. 4. Receiving Emails (IMAP/POP3)

To check an inbox and download messages, connect to the mailbox using MailMan:

mailman.MailHost = “://yourprovider.com”; mailman.PopUsername = “your_username”; mailman.PopPassword = “your_password”; // Fetch headers or full email bundles Chilkat.EmailBundle bundle = mailman.CopyMail(); if (bundle != null) { for (int i = 0; i < bundle.MessageCount; i++) { Chilkat.Email downloadedEmail = bundle.GetEmail(i); Console.WriteLine($“From: {downloadedEmail.FromAddress} - Subject: {downloadedEmail.Subject}”); } } Use code with caution.
