email "from" address is incorrect on outgoing email

I can't figure out why the "from" address in all outgoing email from my network is my.name@website.org... Everywhere I've looked it is set to be support@website.org, which is what it is suppose to be. I checked the settings for "WP Mail SMTP", "eNewsletter", as well as the "Mass Email Sender plugins". Also checked the network admin email settings. Can you think of anywhere else I should be looking? Have you seen this problem before?
