Any ideas on limiting the total number of SMTP messages processed per day?

[Jeff A. Earickson]

Jim,

I would suggest the IPBlock feature of Mailscanner, contained within
CustomConfig.pm.

I have the following in my MailScanner.conf file:

Always Looked Up Last = &IPBlock

Which calls the IPBlock code and allows me to limit smtp msgs per
IP netblock.  It is one of the cooler and less known features of
MailScanner.
