look in your logs:

12:12 00:00 SMTPD(3F7B0174) [212.73.210.73] connect 212.73.210.75 port 2603 12:12 00:00 SMTPD(3F7B0174) [212.73.210.75] HELO mgw1.MEIway.com 12:12 00:00 SMTPD(3F7B0174) [212.73.210.75] MAIL FROM:<owner-postfix-users@postfix.org> 12:12 00:00 SMTPD(3F7B0174) [212.73.210.75] RCPT TO:<lconrad@Go2France.com>

The "connect" ip is the sending machine, your best item to block. Assume ehlo/helo hostname, "mail from: sender@senderdomain" to be bogus.
