Gets or sets whether the connection uses SSL (secure socket layer).
[Visual Basic] Public Property SSLConnection As Boolean
[C#]
public bool SSLConnection {get; set;}
[C++] public: __property bool get_SSLConnection(); public: __property void set_SSLConnection(bool);
[JScript] public function get SSLConnection() : Boolean; public function set SSLConnection(Boolean);
Property Value
TLS 1.2 Encryption
TLS is the successor of SSL, EAGetMail supports SSL 3.0/TLS1.0 - 1.2 very well. In EAGetMail, ConnectTLS doesn't mean TLS encryption, it means TLS command POP3/IMAP protocol.
You don't have to set any property to enable TLS 1.2 encryption. If your server requires TLS 1.2 encryption, TLS 1.2 encryption is used automatically with SSLConnectType.ConnectTLS, SSLConnectType.ConnectSSL or SSLConnectType.ConnectSSLAuto.
To enable TLS 1.2 on Windows 2008/2008 R2/7, please install this update:
https://www.microsoft.com/security/blog/2017/07/20/tls-1-2-support-added-to-windows-server-2008/
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.
