How To Change Email Sender Name on WordPress Site

If your WordPress on Linux site is setup to send emails when users register, forget their passwords, or to send notifications when a new post is published, you may notice the senders email looks a little something like this:
Wordpress <>

This can easily be customized to reflect a different sender name.

From the Linux shell, navigate to /var/www/html/wp-includes and open pluggable.php in your favorite editor. I use vim so my command looks like this:

vim /var/www/html/wp-includes/pluggable.php

Search for the string ‘from_name’. This is done by entering


It should take you to a section that looks like this:

$from_name = 'WordPress';

Change ‘WordPress’ to MyBlog, admin, your name or whatever sender name you’d like to use.

Next, search for the string ‘wordpress@’. This is done entering


There are two areas this needs to be changed. The line of code displays ‘’ Change ‘wordpress’ to admin, your name or whatever username you’d like to use. Possibly one of your domain email accounts. Keep in mind, this only changes the username@, not the domain name itself.

When finished, emails will be coming from:

YourNameofChoice <>


Rename Root Volume Group (VG) on Linux Server

This walk-through worked on a virtual server running RHEL 6.7 in a VMware environment.

As I rebuilt an existing VMware guest that was being scheduled to go into production, I realized I did not rename the default volume group from vg_hostname to rootvg.

You must be root user and it is extremely important to backup the files below. It’s also important to know how to boot up in rescue mode with other boot media in the event there was a typo or other unforeseen issue.

Backup fstab file

cp /etc/fstab /etc/fstab.orig

Backup grub.conf file

cp /boot/grub/grub.conf /boot/grub/grub.conf.orig

Rename volume group

vgrename /dev/vg_OLDname /dev/rootvg

Change all instances of the old volume group in the following files:
Edit /etc/grub.conf (which is a symbolic link to /boot/grub/grub.conf)

vim /etc/grub.conf

Search and replace


Edit fstab file

vim /etc/fstab

Search and replace


Move boot image

mv /boot/initramfs-$(uname -r).img /boot/initramfs-$(uname -r).img.backup
dracut -v /boot/initramfs-$(uname -r).img $(uname -r)
