Hi everyone! I want to allow sasl authentification only from specific networks. I've added smtpd_sasl_exceptions_networks option:
smtpd_sasl_exceptions_networks = !10.0.0.0/8, !192.168.0.0/16, static:all Looks like everything is fine, EHLO doesn't show AUTH for alien networks: 250-example.com 250-PIPELINING 250-SIZE 10240000 250-ETRN 250-STARTTLS 250-ENHANCEDSTATUSCODES 250-8BITMIME 250 DSN BUT I still can use AUTH LOGIN from any IP I want! Am I doing something wrong or have I forgot to add something? Oleg P.S. Postfix version 2.6.6
