Postfix作为hostname.domain.com而不是domain.com发送

我一直在试图设置一个运行postfix的debian邮件服务器，但是当我尝试通过mail [email protected]发送邮件时，收件人将发件人视为hostname.domain.com。 它发送的主机名没有设置A或MXlogging，它只是/ etc / hostname。 如果我通过telnet localhost 25login发送，我可以手动设置发件人为[email protected]。

我的main.cf

 myorigin = mydomian.com myhostname = mail.mydomain.com mydestination = mail.mydomain.com, mydomain.com, localhost, localhost.localdomain relayhost = mynetworks = 127.0.0.0/8 [::ffff:127.0.0.0]/104 [::1]/128 mailbox_size_limit = 0 recipient_delimiter = + inet_interfaces = all alias_maps = hash:/etc/aliases alias_database = hash:/etc/aliases smtpd_tls_cert_file=/etc/ssl/certs/mailcert.pem smtpd_tls_key_file=/etc/ssl/private/mail.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 smtpd_tls_security_level=may smtpd_tls_protocols = !SSLv2, !SSLv3 local_recipient_maps = proxy:unix:passwd.byname $alias_maps 

和mail.log当我发送一封电子邮件

 Aug 3 06:28:51 hostname postfix/pickup[7047]: 4D5432023A: uid=1000 from=<user@hostname> Aug 3 06:28:51 hostname postfix/cleanup[7065]: 4D5432023A: message-id=<[email protected]> Aug 3 06:28:51 hostname postfix/qmgr[7048]: 4D5432023A: from=<[email protected]>, size=339, nrcpt=1 (queue active) Aug 3 06:28:52 hostname postfix/smtp[7067]: 4D5432023A: to=<[email protected]>, relay=mail.destinationserver.com[IP]:25, delay=1.4, delays=0.11/0.01/0.49/0.78, dsn=2.0.0, status=sent (250 Queued (0.110 seconds)) Aug 3 06:28:52 hostname postfix/qmgr[7048]: 4D5432023A: removed 

我已经尝试设置masquerade_domains = mydomain.com但是当我这样做的时候，它在thunderbird和gmail中被标记为垃圾邮件。

• Port25.com SPFtesting失败，gmail SPF通过
• 设置Postfix + Dovecot从数据库读取
• cron：在发生故障时发送电子邮件到不同的地址
• Logwatch不尊重MailFrom
• Exim4不添加DKIM签名
