Question
Where are email messages and other email-related data for my cPanel users stored on the filesystem?
Answer
Email for cPanel users is stored in the following directory:
/home/$user/mail/
Email for a specific email account on a domain is stored in the following directory:
/home/$user/mail/$domain/$email-user/
Path, user/group ID, and obfuscated passwords for email users can be found in these files:
/home/$user/etc/$domain/passwd
/home/$user/etc/$domain/shadow
In the paths above:
$user is the cPanel username
$domain is the domain associated with the cPanel user
$email-user is the email user on the domain
