The Ferrysoft POP3 Module is a Post Office Protocol (POP3) client class to interrogate a POP3 server for available emails, download the emails and return them to the calling program. The POP3 Module is provided in source code form (Visual Basic 2005/2008 compatible and Visual C# 2005/2008 compatible). It is intended for developers, to incorporate into their own applications, in order to provide POP3 client support to the application. The module can be used, royalty-free, by any individual or organisation that purchases the module. As the module is provided in source code form, it can be modified as necessary after purchase, provided that any derived module is not distributed, in source code form, to a third party. The module can be incorporated into a commercial product and sold to third parties, in compiled format, provided that the purpose of the commercial product is not simply to act as a wrapper for the POP3 Module.

The POP3 Module is priced in Pounds Sterling (GBP), US Dollars (USD) and Euros (EUR).

Get the number of messages for the most recently opened mailbox.

Visual Basic

Public ReadOnly Property MessageHeaders _
    As System.Collections.Generic.Dictionary(Of Integer, String)

C#

public System.Collections.Generic.Dictionary<int, string> MessageHeaders { get; }

Get the collection of message headers for the most recently retrieved message. The collection can be accessed sequentially or selectively using any of the following enumerations of Ferrysoft.Pop3.MessageHeaderType:

Bcc

Cc
