GemBox.Email Free Version

Limitations

Free delivers the same performance and set of features as the Professional version. However, the following limitations are imposed:

• Maximum size of a message attachment is 50 KB.
• Maximum number of sent, received, saved, and loaded messages is 50.

The ComponentInfo.FreeLimitReached event allows you to control what happens when your application reaches the free version limit.

First steps

Using the component is easy and straightforward. After referencing .dll from your project, you can use the following code snippet to download an email message using POP protocol:

C# VB.NET

static void Main()
{
    // If using the Professional version, put your serial key below.
    ComponentInfo.SetLicense("FREE-LIMITED-KEY");

    // Create new IMAP client.
    using var imap = new ImapClient("<ADDRESS> (e.g. imap.gmail.com)");
    
    // Connect to IMAP server.
    imap.Connect();

    // Authenticate using the credentials; username and password.
    imap.Authenticate("<USERNAME>", "<PASSWORD>");
}

Sub Main()

    ' If using the Professional version, put your serial key below.
    ComponentInfo.SetLicense("FREE-LIMITED-KEY")

    ' Create new IMAP client.
    Using imap As New ImapClient("<ADDRESS> (e.g. imap.gmail.com)")

        ' Connect to IMAP server.
        imap.Connect()

        ' Authenticate using the credentials; username and password.
        imap.Authenticate("<USERNAME>", "<PASSWORD>")
    End Using
End Sub
