For the sake of documentation, I am going to answer my own question
here.

It appears there is no opposite parm for "ageorder" in scheduler.conf.
You can disable it by commenting out the parm (e.g. "# ageorder") and
restarting zmailer.  Once disabled, scheduler seems to use a random
order instead of a strict age order.  (The answer was found in Matti's
comments in the ChangeLog from 10 May 2003).

If you are experiencing problems (for example, with AOL) where one
message is being rejected so the queue grows and grows for that
channel/host - you will want to make this change.  Be careful you only
have one scheduler.conf - or if like me you have somehow ended up with
more than one of these files in the config directories - change them all
just to be sure).

If you are concerned that randomorder will introduce delivery delays -
don't be.  My observation is zmailer gets rid of messages so fast this
is a non-issue.



Matti - A feature request: it would be nice to implement another parm
named randomorder so the choice between age order and random order is
obvious and can be overridden both globally as well as on individual
channel/hosts.
