Indy POP3 erkennen ob Absender eine Bestätigung will

[Duffy]

Hallo Klaus,
wenn Du die Nachricht/ den Nachrichtenheader empfängst,
function RetrieveHeader(const MsgNum: Integer, AMsg: TIdMessage): Boolean; dann wird sie in eine IdMessage abgelegt. Und hier gibt es die Eigenschaft "ReceiptRecipient"

Zitat von Indy 10 Hilfe:

Return receipt email address.

property ReceiptRecipient: TIdEmailAddressItem;

Description

ReceiptRecipient is a TIdEMailAddressItem property used to identify the address where a return receipt for the message should be delivered. The values in ReceiptRecipient are used in the RFC 2822 message header "Disposition-Notification-To:". A blank value in ReceiptRecipient indicates that a return receipt is not desired.

Use the following properties to get or set the values for the TIdEMailAddressItem:

ReceiptRecipient.Text
ReceiptRecipient.Name
ReceiptRecipient.Address
Including an email address in ReceiptRecipient does not guarantee that a receipt notice will be generated when the message is received; the recipient can always cancel the request.

bye
Claus
