我试图从我的服务器发送邮件使用postfix ，除了一件事情，它完美的作品; 它以root@example而不是[email protected]发送邮件。
这是我的configuration文件，我错过了什么？
# See /usr/share/postfix/main.cf.dist for a commented, more complete version # Debian specific: Specifying a file name will cause the first # line of that file to be used as the name. The Debian default # is /etc/mailname. #myorigin = /etc/mailname smtpd_banner = $myhostname ESMTP $mail_name (Ubuntu) biff = no # appending .domain is the MUA's job. append_dot_mydomain = no # Uncomment the next line to generate "delayed mail" warnings #delay_warning_time = 4h readme_directory = no # TLS parameters smtpd_tls_cert_file=/etc/ssl/certs/ssl-cert-snakeoil.pem smtpd_tls_key_file=/etc/ssl/private/ssl-cert-snakeoil.key smtpd_use_tls=yes smtpd_tls_session_cache_database = btree:${data_directory}/smtpd_scache smtp_tls_session_cache_database = btree:${data_directory}/smtp_scache # See /usr/share/doc/postfix/TLS_README.gz in the postfix-doc package for # information on enabling SSL in the smtp client. smtpd_relay_restrictions = permit_mynetworks permit_sasl_authenticated defer_unauth_destination myhostname = example.com mydomain = example.com smtp_generic_maps = hash:/etc/postfix/generic virtual_alias_domains = example.com alias_maps = hash:/etc/aliases alias_database = hash:/etc/aliases mydestination = example.com, localhost.example.com, localhost relayhost = mynetworks = 127.0.0.0/8 [::ffff:127.0.0.0]/104 [::1]/128 94.23.211.117/24 mailbox_size_limit = 0 recipient_delimiter = + inet_interfaces = all inet_protocols = all #myorigin = /etc/mailname myorigin = example.com # My config home_mailbox = Maildir/ smtpd_sasl_type = dovecot smtpd_sasl_path = private/auth smtpd_sasl_local_domain = smtpd_sasl_security_options = noanonymous broken_sasl_auth_clients = yes smtpd_sasl_auth_enable = yes smtpd_recipient_restrictions = permit_sasl_authenticated,permit_mynetworks,reject_unauth_destination smtp_tls_security_level = may smtpd_tls_security_level = may smtp_tls_note_starttls_offer = yes smtpd_tls_loglevel = 1 smtpd_tls_received_header = yes virtual_alias_maps = hash:/etc/postfix/virtual
如果你需要看看我的虚拟文件和通用文件，他们分别是：
虚拟：
[email protected] root
通用：
root [email protected]
检查/etc/mailname并在/etc/hosts添加一行1.2.3.4 example.com example 。 可能需要在main.cfconfiguration文件中取消注释myorigin行。 这应该是FQDN派生自的最常见的地方。
