Does anyone know if it is possible to control the way sendmail queues messages whilst offline?
I have a user that uses sendmail on his laptop, I understand that when the laptop rejoins the network messages are delivered in reverse order as in a stack type of queue. This has caused some confusion with recipients when email arrives in reverse order. The user has asked me to check to see if it possible to force sendmail to deliver these messages in the order that he wrote them.
Try adding:
define(`confQUEUE_SORT_ORDER', `Time')dnl
to the user's sendmail.mc. The default is `Priority' rather than `Time', which will deliver small items with less recipients first.
Note that the sendmail manual page says:
Creation (submission) time ordering is almost always a bad idea, since it allows large, bulk mail to go out before smaller, personal mail, but may have applicability on some hosts with very fast connections.
Be sure to have the commands:
sendmail -q -Ac sendmail -q
in the script run by the user when the network connection comes up, to force the mail queue to be flushed.
