Outgoing status of the specified email:
emailSentThe email was sent.
emailPendingThe email is waiting to be sent. It is in the spooler.
emailErrorAn error occurred. The error details are returned by ErrorInfo(errMessage).
<Email Identifier>: Integer
Email identifier (variable Email.IdentifiantMail or Property ID of the Email variable initialized when sending the email with functions EmailSend and EmailSendMessage).

Managing emails in asynchronous mode

The email functions are locking functions by default. Which means that no other code can be run during their execution. The program will resume only when the current Email functions have been run.
WEBDEV gives you the ability to manage the emails in asynchronous mode. This mode allows your sites to send emails without locking the execution of other processes.
To use the asynchronous mode, you must:
  1. Uncheck "Disable the email spooler" in the WEBDEV administrator ("Advanced" tab).
  2. Enable the asynchronous mode when starting the SMTP session (with EmailStartSMTPSession or EmailStartSession).
  3. All outgoing emails will be transmitted to a "spooler". Emails are queued up before being sent.
Executing Email functions does no longer block the rest of the program. EmailStatus is used to find out the status of an email.
Remark: If the WEBDEV administrator is closed, the email spooler is cleared: pending emails are not sent and are removed from the spooler.
If there are pending emails, and the "Disable the email spooler" option is checked, the emails will not be lost: the administrator continues to send them, but the spooler will not accept any new emails.
Caution: The asynchronous mode can only be used when starting a session on an SMTP server (EmailStartSMTPSession for sending emails or EmailStartSession). The asynchronous mode is ignored in all other cases.
