How to change sender name from Gitlab emails - email

Question

When I installed Gitlab on one of our servers I didn't realize that the first user would be the Gitlab Admin User and every time Gitlab sends a notification it appears that I'm the one who sends the email (only the name the email is the one in config/gitlab.yml)
How can I change that?
Thanks.

Original answer (July 2014, GitLab 7.8.0)
You can see the sender function in app/mailers/notify.rb#L30:
# The default email address to send emails from
def default_sender_address
address = Mail::Address.new(Gitlab.config.gitlab.email_from)
address.display_name = "GitLab"
address
end
That is the function you could change.
Update July 2016 (2 years later, GitLab 8.9.0+)
The updated code is still in app/mailers/notify.rb
Update Dec. 2018 (GitLab 11.6)
The email specs still shows:
shared_examples 'an email sent from GitLab' do
it 'is sent from GitLab' do
sender = subject.header[:from].addrs[0]
expect(sender.display_name).to eq(gitlab_sender_display_name)
expect(sender.address).to eq(gitlab_sender)
end
Which means some emails are sent with gitlab_sender_display_name, which is defined as:
let(:gitlab_sender_display_name) { Gitlab.config.gitlab.email_display_name }
Changing that gitlab.email_display_name should change the "GitLab" sender.
Harry confirms in the comments:
We now have in /config/initializers/1_settings.rb
Settings.gitlab['email_display_name'] ||= ENV['GITLAB_EMAIL_DISPLAY_NAME'] || 'GitLab'
^^^^^^^^
The ENV part comes from commit 82bfa8f, GitLab v8.4.0v2, Dec. 2015.
