proxy - 绕过代理通过 sendmail 发送电子邮件
问题描述
我公司有一个代理，看起来像 http://somethinglikeproxycompany:3128... 我正在尝试安装 gitlab CE，但发送邮件登录失败。
所以我想先尝试一些简单的东西......
我想从我的 ubuntu 18.04 服务器使用 sendmail 或类似的东西发送邮件。没有防火墙。端口似乎没问题。
任何帮助将不胜感激...
这是我的后缀配置（ /etc/postfix/main.cf ）：
smtpd_banner = $myhostname ESMTP $mail_name (Ubuntu)
biff = no
# appending .domain is the MUA's job.
append_dot_mydomain = no
# Uncomment the next line to generate "delayed mail" warnings
#delay_warning_time = 4h
readme_directory = no
# See http://www.postfix.org/COMPATIBILITY_README.html -- default to 2 on
# fresh installs.
compatibility_level = 2
# TLS parameters
smtpd_tls_cert_file=/etc/ssl/certs/ssl-cert-snakeoil.pem
smtpd_tls_key_file=/etc/ssl/private/ssl-cert-snakeoil.key
smtpd_use_tls=yes
smtpd_tls_session_cache_database = btree:${data_directory}/smtpd_scache
smtp_tls_session_cache_database = btree:${data_directory}/smtp_scache
# See /usr/share/doc/postfix/TLS_README.gz in the postfix-doc package for
# information on enabling SSL in the smtp client.
