我按照这些说明发送邮件,这是 Postfix 日志:

此外,这可能是相关的(来自“ /etc/postfix/main.cf ”):
myhostname = tshepang
mydestination = tshepang, localhost
relayhost =
mynetworks = 127.0.0.0/8 [::ffff:127.0.0.0]/104 [::1]/128
inet_interfaces = all

问题出在 /var/spool/postfix/etc/resolv.conf 文件(chrooted 文件)中。看看它。

您似乎位于代理后面:gmail.com 地址已解析,但 ping 命令未成功。您可以尝试直接连接 gmail 的 SMTP:
nc -w 1 gmail.com 25 ; echo $?

如果它回显“1”,则无法连接,可能是安全过滤的原因。
