You can add NS records to delegate the class of in-addr.arpa block; do not forget to provide a manual local A record to any NS server that receives delegation privileges.

Spam is to send a large amount of junk e-mail electronically. Although the most common medium of spam is e-mail, it is not uncommon for spammers to use instant messaging, text messaging, blogging, web forums, search engines, social media. Spam is not actually a kind of malware, but it is common for malware to spread through spam. This happens when a computer infected with a virus, worm, or other malware distributes spam containing more malware. Users can avoid spam by avoiding unfamiliar e-mails and keeping their e-mail addresses secret as much as possible

Precision shows that messages classified as spam are actually percentages of spam. This is the ratio of true positive (classified as spam and actually spam) to all positive (all emails classified as spam, whether this is the correct classification). In other words, it is the ratio of true positive / (true positive + false positive). Recall or sensitivity indicates that the actual percentage of spam is classified as spam. This is the ratio of words classified as spam for all words that are actually spam (actually classified as spam) (regardless of whether they were correctly classified). It is given by the formula - True Positive / (True Positive + False Negative)
