我在命令行中遇到以下语句的问题：
echo 'Subject: test' | /usr/sbin/sendmail -v <myemail>@gmail.com
它返回以下内容：
# echo 'Subject: test' | /usr/sbin/sendmail -v <email>@gmail.com
[<-] 220 mail.xen.prgmr.com ESMTP Postfix
[->] HELO host.xen.prgmr.com
[<-] 250 mail.xen.prgmr.com
[->] MAIL FROM:<root@hostname.com>
[<-] 250 2.1.0 Ok
[->] RCPT TO:<<email>@gmail.com>
[<-] 554 5.7.1 <<email>@gmail.com>: Relay access denied
sendmail: RCPT TO:<<email>@gmail.com> (554 5.7.1 <<email>@gmail.com>: Relay access denied)
有关如何配置此实际发送的任何线索将不胜感激。这是一些/var/log/mail.log
