Hello, I installed Postfix on CentOS and my "main.cf" file is as below:
myhostname = mail.my-example.com mydomain = my-example.com myorigin = $mydomain ## Uncomment and Set inet_interfaces to all ## inet_interfaces = all ## Change to all ## inet_protocols = all ## Comment ## ##- Uncomment ## mydestination = $myhostname, localhost.$mydomain, localhost, $mydomain ## Uncomment and add IP range ## mynetworks = 127.0.0.0/8, My Public IP ## Uncomment ## home_mailbox = Maildir/ smtpd_use_tls = yes smtpd_tls_cert_file = /etc/postfix/mail.crt smtpd_tls_key_file = /etc/postfix/mail.key smtpd_tls_security_level = may mynetworks_style = subnet queue_directory = /var/spool/postfix When I want to send an email to Yahoo! then it show me below error: # telnet localhost 25 Trying ::1... Connected to localhost. Escape character is '^]'. ehlo localhost 220 mail.my-example.net.com ESMTP Postfix 250-mail.my-example.net.com 250-PIPELINING 250-SIZE 10240000 250-VRFY 250-ETRN 250-STARTTLS 250-ENHANCEDSTATUSCODES 250-8BITMIME 250 DSN mail from:<info> 250 2.1.0 Ok rcpt to:<myexam...@yahoo.com> 554 5.7.1 <myexam...@yahoo.com>: Relay access denied I searched and find a solution as below: "smtpd_recipient_restrictions = permit_sasl_authenticated" But when I added it to main.cf then I can't do anything: # telnet localhost 25 Trying ::1... Connected to localhost. Escape character is '^]'. ehlo localhost How can I solve it? Thank you.
