## Common questions

### What should I check in .env and firewall before running BillionMail?

Replace .env placeholders such as API keys, SECRET_KEY, and your notification email with real settings before use. Also open port 8001 in your firewall and ensure it is not used by another app.

### How do I view default credentials or update the admin password in BillionMail?

Use the bm management command for operations such as bm default to view default login information and bm change to modify the administrator password. You can also use bm update, bm start, bm restart, bm status, and bm stop.

### How can I inspect BillionMail spam filtering with Rspamd?

You can open the Rspamd web interface from BillionMail and check the scan history after sending a test email. This is used when configuring or disabling the spam filter.

### Does BillionMail create cache files that can be cleared?

BillionMail does not generate cache files during normal operation. Its stored data is mainly actual emails or system configurations, and old email data may need to be deleted manually to free SSD space.

### Do I need to warm the IP for BillionMail?

For self-hosted sending, BillionMail is expected to use a dedicated IP and may require IP warming. The source suggests skipping IP warming if you send under 50k emails per month.
