Hello, on my mail server a few days pass through a lot of mails where the sender does not belong to any my domain and also the recipient does not belong to any of my domains. This behavior is strange because I use for send email the SMTP authentication, below log about mail:
http://pastebin.com/SDpVzMVx http://pastebin.com/sUPdSFuH My postfix configuration is: mydestination = $myhostname, localhost.$mydomain, localhost, $mydomain mydomain = mydomain.com myhostname = mail.mydomain.com myorigin = $myhostname relay_domains = $mydestination smtpd_recipient_restrictions = permit_sasl_authenticated, reject_unauth_destination, check_client_access hash:/etc/postfix/client_whitelist, reject_rbl_client bl.spamcop.net, reject_rbl_client dul.dnsbl.sorbs.net, reject_rbl_client zen.spamhaus.org smtpd_sasl_auth_enable = yes smtpd_sasl_local_domain = $myhostname smtpd_sasl_security_options = noanonymous smtpd_sender_restrictions = check_sender_access hash:/etc/postfix/access ..how can I stop the transit of such mail ? I can also set a limit to the number of emails that a user can send in 1 hour ? Thanks. - Salvatore.
