Re: James mail order FIFO resend. Mail Relay

[Klearchos Klearchou]

Hello Stefano,

thank you for your quick reply.
I understand that what I ask is not standard that's why I am willing to
do some codingfor it.

Is it possible to give me some more info regarding what I have to change
or possibly some changes at the confguration file ?

Thank you.

Unfortunately no.

You will have to use 1 thread in the main spool manager, 1 single
processor in the main spoolmanager, 1 thread for remotedelivery and
you will have to write your own RemoteDelivery if you want it to
ignore every message until the older one has been delivered.

What you ask is not supported by the email standards and I think you
won't find any mail server that will try to mimic the behaviour you
need.

And what you are trying to do will only work if you control both the
mail server sending email to james and the mail server receiving email
from james, otherwise they could reorder things.
