# Nextcloud Mail Developer Documentation ## Nightly builds Instead of setting everything up manually, you can just [download the nightly builds](https://nightly.portknox.net/mail/?C=M;O=D) instead. These builds are updated every 24 hours, and are pre-configured with all the needed dependencies. 1. Download 2. Extract the tar archive to 'path-to-nextcloud/apps' 3. Navigate to »Apps«, choose the category »Productivity«, find the Mail app and enable it. The nightly builds are provided by [Portknox.net](https://portknox.net) ## Resetting the app Connect to your database and run the following commands (`oc_` is the default table prefix): ```sql DELETE FROM oc_appconfig WHERE appid = 'mail'; DELETE FROM oc_migrations WHERE app = 'mail'; DROP TABLE oc_mail_accounts; DROP TABLE oc_mail_aliases; DROP TABLE oc_mail_coll_addresses; DROP TABLE oc_mail_attachments; DROP TABLE oc_mail_mailboxes; DROP TABLE oc_mail_messages; DROP TABLE oc_mail_recipients; DROP TABLE oc_mail_classifiers; DROP TABLE oc_mail_trusted_senders; DROP TABLE oc_mail_tags; DROP TABLE oc_mail_message_tags; ```
