Mail sending/delivering order

[Sleidia]

Hello,

I use the following to send 2 emails consecutively:

mail($mess_from_adr, "Message_1", $message_1, "From: $back_to_full", "-f $back_to_adr"
mail($mess_from_adr, "Message_2", $message_2, "From: $back_to_full", "-f $back_to_adr"

The problem is that, when testing it, I sometimes receive message_2 before message_1.

Is there a way I can force the server to deliver messages always in the right order?

No, there isn't.

PHP simply hands the message to its configured mail transfer agent. What the agent does after that gets pretty non-deterministic.

The only thing I can think of that might help is SMTP headers. Try adding the "X-Priority:" header to your messages, one high importance, one low. Maybe set the first to "X-Priority: 2 (high)" and the second to "X-Priority: 4 (low)" is lowest (highest is 1 and lowest is 5).

You might try adding a header of "Precedence: bulk" to the second message. ______________________________________________________________________
