email - 未使用 main.cf 文件中的后缀主机名

Question

我已经使用 mailuits 设置了一个准系统 null Postfix 服务器。

我可以很好地发送电子邮件，但 @domain.tld 始终是 VPS 主机名。这本身并不是错误的，问题是myhostnameinmain.cf没有被使用。

更不用说操作系统主机名将在每次重新启动时重置。

内容/etc/postfix/main.cf如下

# 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 = domain.tld 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

# See http://www.postfix.org/COMPATIBILITY_README.html -- default to 2 on
# fresh installs.
compatibility_level = 2

# TLS parameters
smtpd_tls_cert_file=/etc/letsencrypt/live/domain.tld/cert.pem
smtpd_tls_key_file=/etc/letsencrypt/live/domain.tld/privkey.pem
smtpd_tls_security_level=may

smtp_tls_CApath=/etc/ssl/certs
smtp_tls_security_level=may
smtp_tls_session_cache_database = btree:${data_directory}/smtp_scache
smtp_tls_note_starttls_offer=yes
smtp_tls_loglevel = 1

smtpd_relay_restrictions = permit_mynetworks permit_sasl_authenticated defer_unauth_destination
myhostname = domain.tld
alias_maps = hash:/etc/aliases
alias_database = hash:/etc/aliases
myorigin = /etc/mailname
mydestination = domain.tld, $myhostname, localhost.$mydomain, localhost
relayhost =
mynetworks = 127.0.0.0/8 [::ffff:127.0.0.0]/104 [::1]/128
mailbox_command = procmail -a "$EXTENSION"
mailbox_size_limit = 0
recipient_delimiter = +
inet_interfaces = all
inet_protocols = ipv4
virtual_alias_domains = domain.tld
virtual_alias_maps = hash:/etc/postfix/virtual

hostname终端中的A给了我

root@domain:~# hostname
linux.073fv1.com

每当我收到一封电子邮件时，它都会是from [e-mail]我不想要的。应该是[e-mail]。

我似乎在 conf 文件中找不到任何错误。
