如果我从我的客户端发送电子邮件给其他人，下面我发现与systemctl status -l postfix ：
postfix[20012]: Starting Postfix Mail Transport Agent: postfix. postfix/master[20119]: daemon started -- version 2.11.3, configuration /etc/postfix postfix/qmgr[20121]: 6A07F80F0DF9: from=<...>, size=1812, nrcpt=1 (queue active) postfix/qmgr[20121]: warning: connect to transport private/myhostname: No such file or directory postfix/error[20124]: 6A07F80F0DF9: to=<...>, relay=none, delay=100971, delays=100971/0.01/0/0.1, dsn=4.3.0, status=deferred (mail transport unavailable)
有没有人知道这意味着什么？
这里是postconf -n的输出：
