Bin/mail will use the local sendmail to send mail by default, which requires local machines to install and start the SendMail service, is cumbersome to configure, and can result in unnecessary resource consumption.

If you don't, we can close sendmail.

Turn off the SendMail service

code is as follows

copy code

a.[ Root@sample ~]#/etc/rc.d/init.d/sendmail stop← close SendMail service or [root@sample ~]# service sendmail stop← closed sendmail suit Service Shutting down sendmail: [OK] shutting down sm-client: [OK] B.[root@sample ~]# chkconfig sendmail-off← Turn off SendMail c.[root@sample ~]# chkconfig--list sendmail← confirm that SendMail has been turned off since startup (all is OK) SendMail 0:off 1:off 2:o FF 3:off 4:off 5:off 6:off
