MailServer.Port Property


Gets or sets the port of mail server.

[Visual Basic]
Public Property Port As Integer
[C#]
public int Port {get; set;}
[C++]
public: __property int get_Port();
public: __property void set_Port(int);
[JScript]
public function get Port() : int;
public function set Port(int);

Property Value

A integer value indicating the mail server port. By default, the POP3 port is 110, IMAP4 port is 143, the POP3 SSL port is 995, IMAP4 SSL port is 993. The MailServer Constructor initializes the port by the protocol and sslConnection parameters. For Exchange Web Service/WebDAV protocol, please ignore this property.

Example

[Visual Basic, C#, C++] The following example demonstrates how to receive email with EAGetMail POP3 & IMAP Component, but it doesn't demonstrates the events and mail parsing usage. To get the full samples of EAGetMail, please refer to Samples section.
