Ca m\u0103sur\u0103 preventiv\u0103 \u00eempotriva \u00eenc\u0103rc\u0103rii \u00een timpul livr\u0103rii e-mail-ului, este esen\u021bial s\u0103 te asiguri c\u0103 \u00eenregistr\u0103rile reverse DNS sunt introduse \u0219i configurate corect. Cel mai frecvent motiv pentru stabilirea unei \u00eenregistr\u0103ri reverse DNS este s\u0103 adaugi credibilitate serverului de e-mail care trimite mesaje de ie\u0219ire. Reverse DNS adaug\u0103 urm\u0103rirea suplimentar\u0103 la originea unui e-mail \u0219i unele servere de po\u0219t\u0103 electronic\u0103 primite nu vor accepta e-mailuri de la adrese IP f\u0103r\u0103 un reverse DNS. Acest articol detaliaz\u0103 cum s\u0103 configura\u021bi o zon\u0103 reverse DNS adecvat\u0103 pentru a \u00eembun\u0103t\u0103\u021bi livrarea e-mailurilor.<\/p>\n\n\n\n

Ce este Reverse DNS?<\/h2>\n\n\n\n

Reverse DNS (rDNS) este o rezolu\u021bie de nume care caut\u0103 o adres\u0103 IP pentru a ob\u021bine un nume de domeniu, \u00eendeplinind func\u021bia opus\u0103 a serverului DNS, care transform\u0103 numele de domenii \u00een adrese IP.<\/p>\n\n\n\n

Reverse DNS poate fi folosit ca un filtru de spam. De obicei, utilizatorii de spam utilizeaz\u0103 adrese IP nevalide, adic\u0103 acelea care nu se potrivesc cu numele de domeniu. Un program reverse DNS caut\u0103 adresa IP a unui mesaj primit \u0219i, dac\u0103 nu se g\u0103se\u0219te un nume de domeniu valid, serverul blocheaz\u0103 mesajul. De\u0219i reverse DNS este destul de eficient pentru filtrarea spam-ului, de multe ori blocheaz\u0103 e-mailurile valide.<\/p>\n\n\n\n

Etapele configur\u0103rii Reverse DNS<\/h2>\n\n\n\n

Trebuie s\u0103 creezi un reverse DNS a serverului de nume DNS autorizat pentru adresa IP principal\u0103 a serverul t\u0103u. Pentru aceasta, efectueaz\u0103 urm\u0103toarele etape:<\/p>\n\n\n\n

1.<\/strong> Intr\u0103 in contul t\u0103u My Maghost acces\u00e2nd link-ul AICI<\/a><\/p>\n\n\n\n

Not\u0103: <\/strong> Introdu datele tale de logare corect. \u00cen caz c\u0103 ai dificult\u0103\u021bi, contacteaz\u0103 Centru de Ajutor Maghost. <\/p>\n\n\n\n

2.<\/strong> Dup\u0103 ce am intrat \u00een pagina de admin, acceseaz\u0103 din meniul de sus Domenii web > Manage DNS<\/strong> <\/p>\n\n\n\n

\"\"<\/figure>\n\n\n\n

Pe aceast\u0103 pagin\u0103 ne sunt prezentate toate Reverse DNS existente. <\/p>\n\n\n\n

3.<\/strong> Pentru a configura un Reverse DNS nou, apas\u0103 pe butonul ADD PTR<\/strong>.<\/p>\n\n\n\n

\"\"<\/figure>\n\n\n\n

4. <\/strong>In fereastra nou\u0103 avem urm\u0103toarele c\u00e2mpuri:<\/p>\n\n\n\n

Related Item<\/strong>: alege serviciul dorit<\/p>\n\n\n\n

IP Adress:<\/strong> alege adresa IP <\/p>\n\n\n\n

TTL:<\/strong> un num\u0103r \u00eentreg semnat pe 32 de bi\u021bi care specific\u0103 un interval de timp \u00een care \u00eenregistrarea resurselor poate fi stocat\u0103 \u00een cache \u00eenainte ca sursa informa\u021biei s\u0103 fie consultat\u0103 din nou. Valorile zero sunt interpretate \u00een sensul c\u0103 RR poate fi utilizat doar pentru o tranzac\u021bie \u00een curs \u0219i nu ar trebui s\u0103 fie memorat \u00een cache.<\/p>\n\n\n\n

RDATA:<\/strong> numele PTRD<\/p>\n\n\n\n

\"\"<\/figure>\n\n\n\n

Dup\u0103 ce ai completat formularul, apas\u0103 butonul ADD pentru a salva noul PTR.<\/p>\n\n\n\n

Simplu. Nu? \ud83d\ude09<\/p>\n
