EmailReadLastHeader (Function)

In french: EmailLitEntêteDernier

Reads the header of last email received:

POP3 or IMAP protocol: the Email is stored in the mailbox on the mail server.
via Lotus Notes or Outlook e-mail software: the email received is stored on the local workstation in the Lotus Notes or Outlook inbox.

The variables of the Email structure (or the properties of a variable of type Email) corresponding to the message header are specified.

This function is useful when reading the email is linked to the message size for example.

The Email.Out variable is set to True if no email is found.

Reminder Before reading an Email, you need to log in using EmailStartSession, EmailStartNotesSession or EmailStartOutlookSession.

The POP3 protocol can only be used to read emails.

Example

Example with the Email structure

// Supprime les emails envoyés par des expéditeurs "black-listés" 

EmailStartPOP3Session("utilisateur", "secret", "pop.masociete.fr")

// Parcours des emails
// Lecture de l'entête uniquement 
IF EmailReadLastHeader("utilisateur") THEN
	LOOP
		// Est-ce-que l'expéditeur fait partie d'une 
		// liste de gens "interdit" ?
		IF ExpediteurInterdit(Email.SenderAddress) OR ...
			ExpediteurInterdit(Email.Sender) THEN
			// Si l'email est "interdit", on le supprime
			// Les emails "autorisés" pourront alors être 
			// lus complètement dans un deuxième temps
			EmailDeleteMessage("utilisateur")
		END
	TO DO WHILE EmailReadPreviousHeader("utilisateur")
END
