What the fu**?
Please explain SASI, how is this possible?
Whats the trouble?Yes, SMTP-Proxy blocks most of fake mails and some mails are passed/delivered. I can see a difference of passed mails, there are 5 kb large instead of alle blocked mails with 6kb. Maybe the mail with 5KB are "better" fake mails because the main body is "optimized" and the proxy doesnt recognize this.SMTP-Proxy can not block 100% of all fake mails, but thats normal and okay! Its okay to configure the smtp-proxy with best practise (spam-tab) and use additional RBL-filters. for example we use additional rbl-lists:
and last spam blocker are the enduser, train them so they can recognize those fake mails.
