Postfix 以 root@example 而不是 [email protected] 的身份发送邮件

Question

我正在尝试使用 从我的服务器发送邮件，除了一件事之外，它运行正常；它以 而不是 的postfix形式发送邮件。root@example[email protected]

这是我的配置文件，我遗漏了什么？

# 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

如果你需要查看我的虚拟文件和通用文件，它们分别是：

虚拟的：

[email protected]    root

通用的：

root    [email protected]

检查并添加/etc/mailname一行。您可能需要在 main.cf 配置中取消注释该行。这应该是 FQDN 派生的最常见位置。1.2.3.4 example.com example/etc/hostsmyorigin
