messageId (property)

The Id of the message.

- (NSString*)messageId

- (void)setMessageId:(NSString*)newMessageId

Default Value

""

Remarks

The Id format is as in RFC 2822: id-left@id-right .

A unique Id will automatically be generated on startup. Sending a message will reset id-left if the MessageId has been used in the previous message.

If you set MessageId to a string of the form "@(id-right)" a unique id-left will be generated. If you set MessageId to an empty string, a new MessageId will be generated with the same id-right.

After an MDNReceipt is returned or set, MessageId will contain the Original-Message-ID found in the MDN Receipt.
