后缀：收件人地址被拒绝：HELO/EHLO 无效；必须是 FQDN 或地址文字

发送电子邮件时，我收到未送达的邮件，并显示以下消息“收件人地址被拒绝：HELO/EHLO 无效；必须是 FQDN 或地址文字，而不是“xxx”554 5.7.1“来自某些网络服务器（其中 xxx 是我的 VPS 的名称）。

我检查了日志，没有发现任何可疑的东西。

Postfix 配置如下（应该是相当默认的）：

# 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 (Debian/GNU)
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 = /usr/share/doc/postfix

smtp_tls_session_cache_database = btree:${data_directory}/smtp_scache

smtpd_sender_restrictions = check_sender_access mysql:/etc/postfix/mysql-virtual_sender.cf

我尝试过不同的“smtpd_relay_restrictions“设置但无济于事。

我也检查了垃圾邮件黑名单，但该 IP 似乎没有被列入黑名单（根据 mxtoolbox.com）。

我欢迎任何建议！

运行于 Debian 8.6，postfix 版本 2.11.3

要么更改myhostname为包含域（必须作为该域的 DNS 服务器上的注册表存在，并且可以公开访问），要么保持myhostname原样，并使用以下方式强制使用公共域进行 helosmtp_helo_名称

因此

myhostname = vm19243.domain.com

或者可能是

myhostname = vm19243

smtp_helo_name = mail.domain.com
