Rate Limiting & Spam Protection

Enable rate limiting

Limits repeated submissions from the same IP over a defined window.

Keeping rate limiting enabled is recommended for most public forms.

Max submissions

Maximum submissions allowed during the rate-limit window.

Allowed range:

1 to 100

Within minutes

Length of the rate-limit window.

Allowed range:

1 to 1440

Example:

• Max submissions: 5
• Within minutes: 10

Minimum completion time

Rejects forms submitted unrealistically quickly.

Allowed range:

0 to 60 seconds

Default is a small delay.

Set 0 to disable the timing check.

Allow only one submission per IP address

Prevents a second submission from an IP after one has already been received.

Use carefully because several legitimate users can sometimes share one public IP address.
