Lua mailers scripts now leverages Queue class to implement a mailqueue. Thanks to the mailqueue, emails are still sent asynchronously, but with respect to their generation order (better ordering consistency). That is, previous script limitation (see below) is no longer true: " Current known script limitation: if multiple events are generated simultaneously it is possible that emails could be received out of order since emails are sent asynchronously using smtp_send_email() and there is no sending queue. Relying on the email "date" should help to know which email was generated first.. " For a given server, email-alerts will be sent in the same order as the events were generated. However this does not apply to events between 2 distinct servers, since each server is tracked independently within the lua script. (1 subscription per server, to make sure only relevant servers x events are being tracked and prevent useless wakeups)
