WP From Email Address

I’ve WP Multisite with BuddyPress, I recently used ‘Send From‘ plugin to customize the ‘from email address’ to send a validation link to every new user registering to my website.

The email address by default was ‘[email protected]’ which I wanted to change to ‘[email protected]’. The plugin and / or some other settings that I did to achieve what I wanted changed the validation email address to yet another email address which is ‘[email protected]’.

This gmail address is the address I used to install the WordPress at my hosting.

I will be grateful if someone here can help me reset everything to default. I have already disabled the ‘Send From’ plugin but the emails are still being sent from my Gmail address.

Thanks a lot.
