Hi,
some time ago I wrote a blog post about exactly same topic. See HOWTO: Download emails from a GMail account in C# for details.
Code uses our Rebex Mail component:
using Rebex.Mail;
using Rebex.Net;
...
// create the POP3 client
Pop3 client = new Pop3();
try
{
// Connect securely using explicit SSL.
// Use the third argument to specify additional SSL parameters.
Console.WriteLine("Connecting to the POP3 server...");
client.Connect("pop.gmail.com", 995, null, Pop3Security.Implicit);
// login and password
client.Login(email, password);
// get the number of messages
Console.WriteLine("{0} messages found.", client.GetMessageCount());
// -----------------
// list messages
// -----------------
// list all messages
ListPop3MessagesFast(client); // unique IDs and size only
//ListPop3MessagesFullHeaders(client); // full headers
}
finally
{
// leave the server alone
client.Disconnect();
}
public static void ListPop3MessagesFast(Pop3 client)
{
Console.WriteLine("Fetching message list...");
// let's download only what we can get fast
Pop3MessageCollection messages =
client.GetMessageList(Pop3ListFields.Fast);
// display basic info about each message
Console.WriteLine("UID | Sequence number | Length");
foreach (Pop3MessageInfo messageInfo in messages)
{
// display header info
Console.WriteLine
(
"{0} | {1} | {2} ",
messageInfo.UniqueId,
messageInfo.SequenceNumber,
messageInfo.Length
);
// or download the whole message
MailMessage mailMessage = client.GetMailMessage(messageInfo.SequenceNumber);
}
}
