How to put recaptacha on radicalform?

Question

Joomla

Good afternoon,
The question is the following, I want to put recaptcha on forms created on radicalform, since the hoster swears, as if spam is being sent, I tried to set up sending mail via smtp in the joomla admin panel, so (in my case) yandex refers to the same and blocks the mail account marked SPAM and error 554.

Answer 1

spam can still go through the standard Contacts component, even if the menu item is unpublished.
I faced this. logs helped. the bots substituted a URL without SEF with a call to a contact and filled up the site with spam through it.
check: if there is a card in the component - remove it.

Answer 2

Is it really possible to send spam via forms?
What's in your shipping history?
RadicalForm does not usually generate spam.
Most often, the newsletter goes through the Joomla registration form,

Answer 3

your "handwritten" submissions are available from the outside, use the solutions that are made by the joint efforts of the developers, this allows you to avoid errors that others have already received and prevented.
