我想在我的系统上配置 sendmail，以便每个用户都可以发送电子邮件。我按照https://stackoverflow.com/questions/10359437/sendmail-how-to-configure-sendmail-on-ubuntu但得到
Jan 25 19:12:39 regDesktopHome sendmail[32386]: t0Q3CdAt032386: from=root, size=39, class=0, nrcpts=1, msgid=<[email protected]>, relay=root@localhost

Jan 25 19:14:20 regDesktopHome sendmail[32455]: NOQUEUE: SYSERR(ron): /etc/mail/sendmail.cf: line 0: cannot open: Permission denied
当/var/log/mail.log我执行时为什么会出现错误？echo "My test email being sent from sendmail" | sudo /usr/sbin/sendmail [email protected]Temporary system failure
谢谢！
