SPF record
/spf-recordЗапис SPF є різновидом запису DNS. Одержувач може перевірити запис SPF, щоб визначити, чи було повідомлення відправлене з вашого домену чи відіслав авторизованим поштовим сервером. Принцип роботи технології SPF полягає в наступному: SPF дозволяє власнику домену, вказати список серверів, що мають право відправляти email-повідомлення зі зворотними адресами в цьому домені. Агенти передачі пошти, що отримують поштові повідомлення, можуть запитувати SPF-інформацію за допомогою простого DNS-запиту, верифікуючи таким чином сервер відправника. Стандартний запис виглядає так: example.org.
