Does anyone know a way to set the message size restriction based on

In the AM I have a large volume of outgoing traffic. If users send
large messages it exceeds the bandwith of the circuit.
The AM messages are time sensitive so max outgoing performance is
critical.
In the PM there is very light volume so large messages are not a
problem. The PM messages are not time sensitive so slower performance
isn't an issue.
This is a dedicated list server so if I can restrict the size of
incoming mail based on time of day it will also limit the size of the
outgoing.
Thanks...
You need a policy daemon that supports ACLs by time.
Make sure to use a 450 response code so a mailer will try again later.
Note: this will NOT work on items you are sending out that do not come
in via smtpd (aka sendmail command).
A quick check finds www.apolicy.org but I'm sure there are others. (No
experience with this one, so YMMV.)
Ralf also has a suggestion.
