Wordpress uses PHP mail() by default. If you disable/uninstall any extensions that try to manage email sending and delete the configuration lines above from
wp-config.php
, it should work fine.You can check if PHP’s mail() function is working properly by creating a file with the following content:
Place it in your document root (e.g.
/var/www/html
) and browse to it. If it’s blank, everything went well and you should receive an email shortly.PHP uses an MTA to send it’s mails trough mail(), if you want to override it on system level you could edit
/etc/postfix/main.cf
and addif you are on an older system, you might need to configure
sendmail
instead
