By default, Qmail delivers mail to the Maildir directory within the user's home directory. The Maildir directory is a special format for storing email messages that is optimized for efficient delivery and retrieval.
To deliver mail to the Maildir directory within the user's home directory, Qmail uses the ~/.qmail file to determine the location of the Maildir directory. The ~/.qmail file is a configuration file that specifies the delivery instructions for incoming email.
To deliver mail to the Maildir directory within the user's home directory, you can create a ~/.qmail file with the following contents:
./Maildir/
This will instruct Qmail to deliver mail to the Maildir directory within the user's home directory.
It's important to note that the ~/.qmail file must be owned by the user and must have the correct permissions to allow Qmail to access it. You may also need to make additional configuration changes to Qmail to enable mail delivery to the Maildir directory within the user's home directory. Consult the Qmail documentation and online resources for more information on how to configure Qmail to deliver mail to the Maildir directory within the user's home directory.
