The certificate to enable the SSL connection.
[Visual Basic] Public Property ClientCertificate As Certificate
[C#]
public Certificate ClientCertificate {get;}
[C++] public: __property Certificate^ get_ClientCertificate();
[JScript] public function get ClientCertificate() : Certificate;
Property Value
Remarks
Most email servers don't require client certificate.
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.
