Stored procedures
Returns the number of incoming messages currently found:
  • on the email server (POP3 and IMAP protocol).
    • POP3 protocol: This number of messages remains constant during the entire email session, even if new emails are received or if emails are deleted by EmailDeleteMessage.
    • IMAP protocol: This number of messages evolves according to the incoming emails or to the emails actually deleted from the email server (via an "expunge" commande, clear the bin from a WebMail for example). You also have the ability to force the destruction of all deleted emails via EmailExpunge.

Remarks

Deleted messages (POP3 protocol)

If a message was deleted by EmailDeleteMessage:
  • EmailNbMessage returns the number of messages on the email server before they are deleted.
  • the message numbers are not re-assigned.
Therefore, if four messages are found on the server at the beginning of session, these messages are numbered from 1 to 4. If message #1 is deleted:
  • EmailNbMessage used in the same session always returns 4.
  • Message 1 cannot be read by EmailReadMessage because the message does not exist anymore (only messages 2, 3 and 4 exist).
The message numbers are re-assigned during the next connection.

Deleted messages (IMAP protocol)

If a message was deleted by EmailDeleteMessage, this message is actually deleted from the session:
  • during the next "expunge" command (clear the bin from a WebMail for example).
  • Versions 20 and later
    when using EmailExpunge to force all the deleted emails to be destroyed.
    New in version 20

New messages (POP3 protocol)

The POP3 protocol cannot be used to find out and manage the new messages received during the connection. To get the new messages, you must disconnect (EmailCloseSession) and reconnect (EmailStartSession).
