Uploading emails using IMAP

Uploading emails to the IMAP server is fairly easy with Mail.dll IMAP client

First we’ll use Mail.dll to upload an existing email in eml format to the IMAP server:

// C# code

using (Imap imap = new Imap())
{
    imap.Connect("server");
    imap.Login("user", "password");

    string eml = File.ReadAllText("email.eml", Encoding.GetEncoding(1252));

    // The name of the folder depends on your IMAP server
    imap.UploadMessage("[Gmail]/Sent Mail", eml);

    imap.Close();
}

' VB.NET code

Using imap As New Imap()
	imap.Connect("server")
	imap.Login("user", "password")

	Dim eml As String = File.ReadAllText("email.eml", Encoding.GetEncoding(1252))

	' The name of the folder depends on your IMAP server
	imap.UploadMessage("[Gmail]/Sent Mail", eml)

	imap.Close()
End Using

Second sample shows how to create new email message and upload it to IMAP server.

// C# code

using (Imap imap = new Imap())
{
    imap.Connect("server");
    imap.Login("user", "password");

    // Create new mail message
    MailBuilder builder = new MailBuilder();
    builder.Subject = "subject";
    builder.From.Add(new MailBox("alice@email.com", "Alice"));
    builder.To.Add(new MailBox("bob@email.com", "Bob"));
    builder.Text = "This is plain text email";

    // Upload
    // The name of the folder depends on your IMAP server
    imap.UploadMessage("[Gmail]/Sent Mail", builder.Create());

    imap.Close();
}

' VB.NET code

Using imap As New Imap()
	imap.Connect("server")
	imap.Login("user", "password")

	' Create new mail message
	Dim builder As New MailBuilder()
	builder.Subject = "subject"
	builder.From.Add(New MailBox("alice@email.com", "Alice"))
	builder.[To].Add(New MailBox("bob@email.com", "Bob"))
	builder.Text = "This is plain text email"

	' Upload
	' The name of the folder depends on your IMAP server
	imap.UploadMessage("[Gmail]/Sent Mail", builder.Create())

	imap.Close()
End Using

Please note that only few IMAP servers are going to send the message to the actual recipients. Most servers will only upload the message without sending it.
You should use SMTP protocol for this.
