Of course!

It supports several different formats.
Cut straight from /etc/MailScanner/rules/README, here they are:
    192.168.21.        # Any SMTP client IP address in this network
    192.168.21        # Any SMTP client IP address in this network
    192.168.21.0/255.255.255.0 # Any SMTP client IP address in this network
    192.168.21.0/24        # Any SMTP client IP address in this network
    /pattern-with-no-letters/ # Any SMTP client IP address matching this
                  # Perl regular expression
    /^192\.168\.1[4567]\./    # Any SMTP client IP address in the networks
                # 192.168.14 - 192.168.17
