Warning to all owners of .rs domains who have email addresses with info@ or office@, they have received an email apparently from SBB and allegedly sent from the admin@eunet.co.rs email address that they need to make a payment. This email is probably marked as SPAM, but if it is not, in any case, ignore the email and contact your domain registrar for confirmation.
Regarding this problem, which has quite alarmed most owners, two articles will be posted today, one is how to tell if the email is original and not sent from a fake address, and the other is a notification that a new spam rule for spamassassin related to the SPF record will be set on all servers, where the score will automatically be 99 if it is not correct. Setting up an SPF record is extremely easy and every domain and properly configured email server should have one.
