Mail location is wrong

[server staff]

Hi Team,

I'm facing an issue on roundcube for last 3 days. Please anyone help me to solve it.

* My linux server contains virtualmin, postfix for smtp, Postfixadmin for admin the mail accounts, dovecot for IMAP/POP.
* I have seen that the path of the mail location of each email account in the postfix (db name is "mails") is /home/virtual_mail/$domain_name/$user. The whole mails are coming to this location.
* In the same time, the dovecot's mail location is configured in /home/virtual_mail/$user@$domain_name. I think the roundcube is trying to take mails from this location and seems blank when I logged in the mail account.

Please help me to configure the mail location of the dovecot to  "/home/virtual_mail/$domain_name/$user". If you need any more information, please update. This is very urgent, my clients are still sending mails, but I can't see the mails on my inbox.

Thank you.

You need to change Dovecot's configuration then, not Roundcube's.
