PEAR Mail_Queue sending duplicate emails

Question

Here are a couple of questions:

Is mail_queue->put supposed to insert a message twice in the database? The only differences are the time_to_send value and the user_id.

This is what I get for a single message for one user:

1. user_id = 1, time_to_send = 2009-02-10 14:02:02
2. user_id = -1, time_to_send = 2009-02-10 14:00:02

The first one is what I would expect, but what purpose does the second one serve?

If I send the queue, the message will arrive twice. If I delete the one with the negative user_id, only a single mail gets sent.

Answer 1

I went through the program line-by-line and sure enough, there was an uncommented example for the put function.

Answer 2

function put($from, $to, $hdrs, $body, $sec_to_send=0, $delete_after_send=true, $id_user=MAILQUEUE_SYSTEM)

Do you pass the parameter $id_user or is it the default value?
