The present systems of electronic mail, have been based on needs and rules designed for many years, in the beginnings of Internet.

Nowadays, any person with minimum knowledge, can form a direction of mail of a dominion of existing Internet and come to send thousands of messages in her name or the name of that company. Doubt does not fit that this type of activities important losses of corporative image and time entail.

In order to mitigate this, from Igarcom we have implanted SPF in the dominions of our clients of shared lodging. SPF widely is used in Internet, but of very little form in Spain. For that reason, from Igarcom we want to be first in facilitating this protection. Companies like Google, Microsoft, Ebay, Youtube, etc… use these protections for a long time to avoid that their dominions are used illegally.
