The messages placed in this category are messages that are refused at entry because of their origin (open relay, blacklisted IP, etc.) or the way in which they were configured to be sent (mass attack, non-respect of the SPF field, etc.). This verification is carried out as soon as the e-mail is received, before the anti-spam analysis. When an e-mail is categorised as "R. spam", the system asks the server that sent the e-mail to re-present it later. Therefore, this type of mail is not kept on our system and therefore cannot be released. Note: the re-sending request is a precaution against spammers who, given the considerable size of their mail flow, do not re-send mails
