Hi all, I've used Postfix/Postcreen to protect zombies/spambots to our email system. Currently, I've setup the pregreet test of Postscreen as configuration below: In main.cf: postscreen_access_list = permit_mynetworks, cidr:/etc/postfix/postscreen_access.cidr postscreen_blacklist_action = enforce postscreen_dnsbl_threshold = 3 postscreen_dnsbl_sites = zen.spamhaus.org*3 bl.mailspike.net*3 b.barracudacentral.org*2 postscreen_dnsbl_action = enforce postscreen_dnsbl_ttl = 1h postscreen_greet_banner = $smtpd_banner postscreen_greet_wait = 6s postscreen_greet_action = enforce
I donot know how to demonstrate the test "postscreen_greet_wait" to know that Postscreen is protecting zombies/spambots that speak before its turn. Any tools or ways for this test? Regards, Thang
