So, I logged into mysql as the root admin. I looked through the databases and noticed there was a psa db which I am assuming stands for Plesk Server Administration. I immediately looked for email and finally saw mail. I saw all of the usernames and a quick join with the domains table showed me which column belonged to which domain.
SELECT mail.mail_name, domains.name from mail LEFT OUTER JOIN domains ON domains.id = mail.dom_id;
But, now I needed to find the passwords for these. After some more hunting, I found the accounts table where passwords are stored in plain text. If only I didn’t have 200 to look through. So a query was in order:
SELECT accounts.id, mail.mail_name, accounts.password, domains.name FROM domains LEFT JOIN mail ON domains.id = mail.dom_id LEFT JOIN accounts ON mail.account_id = accounts.id
