Pop3Connect Method (String, Int32, Boolean)
Connects to a POP3 server.

Namespace: MailBee.Pop3Mail
Assembly: MailBee.NET (in MailBee.NET.dll) Version: 11.2.0 build 590 for .NET 4.5
Syntax
public bool Connect(
	string serverName,
	int port,
	bool pipelining
)

Parameters

serverName
Type: SystemString
The name or IP address of the POP3 server.
port
Type: SystemInt32
The port on which to communicate with the server. The standard POP3 port is 110. For TLS/SSL connections, dedicated port is 995 (however, TLS/SSL connections via regular port are possible too, see SslMode and StartTls topics).
pipelining
Type: SystemBoolean
Specifies whether to use commands pipelining if it's supported by the server.

Return Value

Type: Boolean
true if a connection attempt succeeded; otherwise, false.
Exceptions
ExceptionCondition
MailBeeExceptionAn error occurred and ThrowExceptions is true.
Remarks
If pipelining is true and the server supports pipelining, MailBee will join POP3 commands in batches whenever possible, providing major performance boost in scenarios when multiple messages are downloaded or deleted at once. The methods which take advantage of pipelining are: DownloadMessageHeaders(Int32, Int32, Int32), DownloadEntireMessages(Int32, Int32), DeleteMessages(Int32, Int32), and their asynchronous versions (BeginDownloadMessages(Int32, Int32, Int32, AsyncCallback, Object), BeginDeleteMessages(Int32, Int32, AsyncCallback, Object)). The performance may increase 10+ times if many messages (20 and more) are processed.
Note Note
By default, MailBee can autodetect if the mail server you're connecting to requires SSL connection (this works for well-known mail services like gmail.com or live.com). To disable SSL mode and port autodetection, set AutodetectPortAndSslMode to false.
Examples
This sample connects to the POP3 server, downloads headers for the first 5 messages, and displays them. If the server supports pipelining, all 5 message headers will be downloaded in a single round-trip to the server.
// To use the code below, import MailBee namespaces at the top of your code
using MailBee;
using MailBee.Pop3Mail;
using MailBee.Mime;

// The actual code (put it into a method of your class)
Pop3 pop = new Pop3();
pop.Connect("mail.domain.com", 110, true);
pop.Login("jdoe", "secret");
MailMessageCollection msgHeaders = pop.DownloadMessageHeaders(1, 5);
foreach (MailMessage msgHeader in msgHeaders)
{
    Console.WriteLine("Message #" + msgHeader.IndexOnServer + ":\r\n" + msgHeader.RawHeader);
}
pop.Disconnect();
