You can try this plugin for example: https://wordpress.org/plugins/wp-smtp/
Setting an external SMTP server, such as GMail should work. However, GMail requires authentication. Please find the necessary details for SMTP setup below.
Mailer: smtp
SMTP Authentication: yes
SMTP Security: SSL
SMTP Port: 465
SMTP Username: your gmail full address
SMTP Password: your gmail password
SMTP Host: smtp.gmail.com
