Hi there, i wanna use the ispconfig smtp to send email from my LAN server. I've added the ip adresses or subnet in the variable mynetworks as follow in my /etc/postifx/main.cf Code: mynetworks = 127.0.0.0/8, [::1]/128, 82.193.35.122 This trick always worked for me, but now with this configuration i'll get Code: May 13 11:16:08 ns2 postfix/smtps/smtpd[2830]: NOQUEUE: reject: RCPT from host35-122.82-193.overlinx.net[82.193.35.122]: 554 5.7.1 <host35-122.82-193.overlinx.net[82.193.35.122]>: Client host rejected: Access denied; from=<[email protected]> to=<[email protected]> proto=ESMTP helo=<mail.domain.tld> Any idea?
