我有一个带有一些虚拟机的 XEN 服务器，其中之一是电子邮件服务器。
如何告诉 DOM0 将所有根电子邮件发送到我的管理电子邮件（位于电子邮件虚拟机内）？
我尝试安装msmtpd并添加配置文件/etc/msmtprc：
# A system wide configuration file is optional.
# If it exists, it usually defines a default account.
# This allows msmtp to be used like /usr/sbin/sendmail.
account default
# The SMTP smarthost
host mail.myOtherVM.de
# Use TLS on port 465
port 587
tls on
tls_starttls on
# Construct envelope-from addresses of the form "[email protected]"
from %[email protected]
# Syslog logging with facility LOG_MAIL instead of the default LOG_USER
syslog LOG_MAIL
但是当尝试发送电子邮件时
echo -e "Subject: msmtp test\nhello test." | msmtp [email protected]
在我的电子邮件虚拟机上，我收到错误：
lost connection after DATA from unknown[2a01:xxxx:1d02::2]
disconnect from unknown[2a01:xxxx:1d02::2] ehlo=2 starttls=1 mail=1 rcpt=0/1 data=0/1 commands=4/6
（我也尝试过 465 端口，但该端口根本没有打开。）
答案1
msmtp仅适用于用户名和密码，例如/etc/msmtprc：
defaults
# Use TLS on port 465
port 587
tls on
tls_starttls on
# Syslog logging with facility LOG_MAIL instead of the default LOG_USER
syslog LOG_MAIL
# Mail account
account [email protected]
from yourserver dom0 <[email protected]>
# Host name of the SMTP server
host mail.yourserver.de
auth on
user [email protected]
password yourpass
account default: [email protected]
请注意卸载任何未配置的其他 MTA 并安装msmtp-mta（它将 sendmail 符号链接到 msmtp）
