Retrieves all emails' information from POP3/IMAP4/MS Exchange Server.
[Visual Basic] Public Function GetMailInfos( _ ) As MailInfo() Public Async Function GetMailInfosAsync( _ ) As Task (Of MailInfo())
[C#] public MailInfo[] GetMailInfos( ); public async Task<MailInfo[]> GetMailInfosAsync( );
[C++] public: array<MailInfo^> GetMailInfos( );
[JScript] public function GetMailInfos( ) : MailInfo [];
Return Value
Remarks
By default, this method returns all emails in "INBOX". You can use SelectFolder method to retrieve email list in selected folder.
GetMailInfosParam property can set some filters for returned email list on server.
For example, you can use GetMailInfosParam property to retrieve only unread/new email(s) from server, then use MailClient.MarkAsRead method to mark the email as read to prevent retrieving the same email again.
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.
