If desired, you may allow users to upload and [attach files to notifications](publish.md#attachments). To enable
this feature, you have to simply configure an attachment cache directory and a base URL (`attachment-cache-dir`, `base-url`).
Once these options are set and the directory is writable by the server user, you can upload attachments via PUT.
By default, attachments are stored in the disk-case **for only 3 hours**. The main reason for this is to avoid legal issues
and such when hosting user controlled content. Typically, this is more than enough time for the user (or the phone) to download
the file. The following config options are relevant to attachments:
By default, attachments are stored in the disk-cache **for only 3 hours**. The main reason for this is to avoid legal issues
and such when hosting user controlled content. Typically, this is more than enough time for the user (or the auto download
feature) to download the file. The following config options are relevant to attachments:
* `base-url` is the root URL for the ntfy server; this is needed for the generated attachment URLs
* `attachment-cache-dir` is the cache directory for attached files

* `visitor-request-limit-replenish` is the rate at which the bucket is refilled (one request per x). Defaults to 10s.
### Attachment limits
Aside from the global file size and total attachment cache limits (see [above](#attachments)), there are two relevant
per-visitor limits:
XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXx
* `visitor-attachment-total-size-limit` is the total storage limit used for attachments per visitor. It defaults to 100M.
The per-visitor storage is automatically decreased as attachments expire. External attachments (attached via `X-Attach`,
see [publishing docs](publish.md#attachments)) do not count here.
* `visitor-attachment-daily-bandwidth-limit` is the total daily attachment download/upload bandwidth limit per visitor,
including PUT and GET requests. This is to protect your precious bandwidth from abuse, since egress costs money in
most cloud providers. This defaults to 500M.
### E-mail limits
Similarly to the request limit, there is also an e-mail limit (only relevant if [e-mail notifications](#e-mail-notifications)

variable before running the `ntfy` command (e.g. `export NTFY_LISTEN_HTTP=:80`).
| Config option | Env variable | Format | Default | Description |
|---|---|---|---|---|
| `base-url` | `NTFY_BASE_URL` | *URL* | - | Public facing base URL of the service (e.g. `https://ntfy.sh`) |
| `listen-http` | `NTFY_LISTEN_HTTP` | `[host]:port` | `:80` | Listen address for the HTTP web server |
| `listen-https` | `NTFY_LISTEN_HTTPS` | `[host]:port` | - | Listen address for the HTTPS web server. If set, you also need to set `key-file` and `cert-file`. |
| `key-file` | `NTFY_KEY_FILE` | *filename* | - | HTTPS/TLS private key file, only used if `listen-https` is set. |
| `cert-file` | `NTFY_CERT_FILE` | *filename* | - | HTTPS/TLS certificate file, only used if `listen-https` is set. |
| `firebase-key-file` | `NTFY_FIREBASE_KEY_FILE` | *filename* | - | If set, also publish messages to a Firebase Cloud Messaging (FCM) topic for your app. This is optional and only required to save battery when using the Android app. See [Firebase (FCM](#firebase-fcm). |
| `cache-file` | `NTFY_CACHE_FILE` | *filename* | - | If set, messages are cached in a local SQLite database instead of only in-memory. This allows for service restarts without losing messages in support of the since= parameter. See [message cache](#message-cache). |
| `cache-duration` | `NTFY_CACHE_DURATION` | *duration* | 12h | Duration for which messages will be buffered before they are deleted. This is required to support the `since=...` and `poll=1` parameter. Set this to `0` to disable the cache entirely. |
| `attachment-cache-dir` | `NTFY_ATTACHMENT_CACHE_DIR` | *directory* | - | Cache directory for attached files. To enable attachments, this has to be set. |
| `attachment-total-size-limit` | `NTFY_ATTACHMENT_TOTAL_SIZE_LIMIT` | *size* | 5G | Limit of the on-disk attachment cache directory. If the limits is exceeded, new attachments will be rejected. |
| `attachment-file-size-limit` | `NTFY_ATTACHMENT_FILE_SIZE_LIMIT` | *size* | 15M | Per-file attachment size limit (e.g. 300k, 2M, 100M). Larger attachment will be rejected. |
| `attachment-expiry-duration` | `NTFY_ATTACHMENT_EXPIRY_DURATION` | *duration* | 3h | Duration after which uploaded attachments will be deleted (e.g. 3h, 20h). Strongly affects `visitor-attachment-total-size-limit`. |
| `keepalive-interval` | `NTFY_KEEPALIVE_INTERVAL` | *duration* | 55s | Interval in which keepalive messages are sent to the client. This is to prevent intermediaries closing the connection for inactivity. Note that the Android app has a hardcoded timeout at 77s, so it should be less than that. |
| `manager-interval` | `$NTFY_MANAGER_INTERVAL` | *duration* | 1m | Interval in which the manager prunes old messages, deletes topics and prints the stats. |

| `visitor-attachment-total-size-limit` | `NTFY_VISITOR_ATTACHMENT_TOTAL_SIZE_LIMIT` | *size* | 100M | Total storage limit used for attachments per visitor, for all attachments combined. Storage is freed after attachments expire. See `attachment-expiry-duration`. |
| `visitor-attachment-daily-bandwidth-limit` | `NTFY_VISITOR_ATTACHMENT_DAILY_BANDWIDTH_LIMIT` | *size* | 500M | Total daily attachment download/upload traffic limit per visitor. This is to protect your bandwidth costs from exploding. |
