CentOS Setup SendMail sender, let sendmail not show through XXX generation

0. There is a very fast way

Command: hostname itzhanzhang.com, but the restart will not work, so please continue to look down once and for all methods:

1. Set your host name

The default hostname is similar to "Vm_24_76_centos" and the email address is "sent by <[email protected]_24_76_centos>"

And we do not like this address, you can modify the/etc/sysconfig/network file, modify the host name, such as my domain name is itzhanzhang.com, I can be modified as: hostname=itzhanzhang.com

2. Modify the SendMail domain name

Edit the/etc/mail/local-host-names file, add a domain name, such as my Itzhanzhang, can be modified as:

3. Modify the DNS server address

If there is no letter, there may be a problem with the DNS server, you can modify the/etc/resolv.conf file, I do not have a problem, it is not modified, such as:

4. Restart the Network Service

Command: Service Network restart

5. Test letters

This time the sender of [email protected] is displayed. I use the root user, it shows "[email protected]"

6. You can also modify the sender by modifying the php.ini file

Code: Sendmail_path =/usr/sbin/sendmail-f [email protected]-t-i
