正如标题所示，我正在努力让邮件服务器发送电子邮件。
我最近购买了一个 VPS 用于托管，目前正在尝试设置邮件服务器，该服务器现在可以接收电子邮件但仍然无法发送。
这是我的 postfix main.cf：
# 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
# See http://www.postfix.org/COMPATIBILITY_README.html -- default to 2 on
# fresh installs.
compatibility_level = 2
# TLS parameters

考虑到我对服务器管理还很陌生，在尝试这样的任务之前可能需要学习更多一些，有谁知道我可能做错了什么？
