我使用以下命令在我的服务器上安装了sendmail：
sudo apt-get install sendmail sudo sendmailconfig 在运行sudo sendmailconfig之前sudo sendmailconfig ive将我的服务器主机名添加到我的/etc/hosts 。 现在当我尝试运行sendmail的时候，
> echo "Subject: sendmail test" | sendmail -v [email protected] [email protected]... Connecting to [127.0.0.1] via relay... 220 localhost.localdomain ESMTP Sendmail 8.15.2/8.15.2/Debian-3; Sun, 12 Nov 2017 13:02:49 GMT; (No UCE/UBE) logging access from: localhost(OK)-localhost [127.0.0.1] >>> EHLO localhost.localdomain 250-localhost.localdomain Hello localhost [127.0.0.1], pleased to meet you 250-ENHANCEDSTATUSCODES 250-PIPELINING 250-EXPN 250-VERB 250-8BITMIME 250-SIZE 250-DSN 250-ETRN 250-AUTH DIGEST-MD5 CRAM-MD5 250-DELIVERBY 250 HELP >>> VERB 250 2.0.0 Verbose mode >>> MAIL From:<[email protected]> SIZE=23 [email protected] 250 2.1.0 <[email protected]>...

我不知道如何解决这个问题。 我启用了防火墙，但是所有出站端口都是允许的。
电子邮件被添加到邮件队列，但超时。
