Fa'afefea ona Fa'amaonia lau Fa'amaoniga Imeli ua Fa'atulaga Sa'o (DKIM, DMARC, SPF)

DKIM Validator DMARC SPF

Afai o lo'o e lafoina imeli i so'o se ituaiga voluma, ose pisinisi lea e ta'usala ai oe ma e tatau ona fa'amaonia lou mama. Matou te galulue faʻatasi ma le tele o kamupani o loʻo fesoasoani ia i latou i le latou femalagaiga imeli, faʻamafanafanaina o le IP, ma faʻafitauli o le tuʻuina atu. O le tele o kamupani latou te le iloa o loʻo iai a latou faʻafitauli.

O Faafitauli Le Vaaia o le Fa'asaoina

E tolu faʻafitauli e le o vaʻaia ma le faʻafeiloaʻiina o imeli e le o iloa e pisinisi:

  1. Faatagaga - Imeli e tu'uina atu auaunaga (ESP) pulea le fa'atagaga e filifili ai... ae o le 'au'aunaga i luga ole laiga (ISP) pulea le faitotoa mo le tuatusi imeli o le a taunuu. E matua leaga lava faiga. E mafai ona e faia mea uma o se pisinisi e maua ai faʻatagaga ma tuatusi imeli, ma e leai se manatu o le ISP ma e mafai ona poloka oe.
  2. Pusa Initaneti – ESP fa'alauiloa maualuga laveaʻiina fua faatatau e matua le aoga. O se imeli e ave sa'o i le pusa lapisi ma e le'i va'aia lava e lau tagata fai imeli e tu'uina atu fa'apitoa. Ina ia mataitu moni lau pusa meli tuu, e tatau ona e fa'aogaina se lisi o fatu ma alu e va'ai i ISP ta'itasi. E iai auaunaga e faia ai lea tulaga.
  3. Faʻailoga - ISP ma isi vaega 'au'aunaga e fa'atumauina fo'i sikola ta'uleleia mo le tu'uina atu o le tuatusi IP mo lau imeli. O lo'o iai lisi uliuli e mafai ona fa'aoga e ISP e poloka uma ai au imeli, po'o le leaga o lou ta'uleleia e ono fa'asesē ai oe i le fa'ailoga leaga. E iai le tele o au'aunaga e mafai ona e fa'aogaina e mata'ituina ai lou igoa IP… ae o le a fai si ou le mautonu talu ai o le to'atele e leai se malamalamaga i ISP ta'itasi algorithms.

Email Authentication

O faiga sili mo le faʻaitiitia o soʻo se faʻailoga faʻapipiʻi pusa o le faʻamautinoa ua e setiina se numera o faʻamaumauga DNS e mafai e le ISP ona faʻaogaina e suʻe ai ma faʻamautinoa o imeli o loʻo e lafoina e lafo moni e oe ae le o se tasi e faafoliga o lau kamupani. . E faia lenei mea e ala i le tele o tulaga:

  • Auina Faʻavae Faʻavae Faʻavae (SPF) - o le tulaga pito i leva, o le mea lea e te resitalaina ai se TXT faʻamaumauga i luga o lau resitalaina (DNS) o loʻo taʻu mai ai poʻo a domains poʻo tuatusi IP o loʻo e lafoina mai ai imeli mo lau kamupani. Mo se faʻataʻitaʻiga, ou te lafoina imeli mo Martech Zone mai Google workspace ma mai CircuPress (o la'u lava ESP i le taimi nei i le beta). E i ai laʻu mea faʻapipiʻi SMTP i luga o laʻu upega tafaʻilagi e lafo foi e ala i Google, a leai semanu ou te i ai se tuatusi IP e aofia ai foi i lenei mea.

  • Domain-fa'avae Fa'amaumauga Fa'amaoni, Lipoti ma le Fa'amalieina (DMARC) - o lenei tulaga fou o loʻo i ai se ki faʻailoga i totonu e mafai ona faʻamaonia uma laʻu vaega ma le tagata e auina atu. O ki ta'itasi e gaosia e la'u tagata e lafo, ma fa'amautinoa e le mafai ona fa'a'ole'ole imeli na lafo mai e se tagata fa'asalalau. Afai o lo'o e fa'aogaina le Google Workspace, o lea faʻafefea ona seti DMARC.
  • DomainKeys Meli Fa'ailoa (DKIM) - Galulue faʻatasi ma le DMARC faʻamaumauga, o lenei faʻamaumauga e logoina ai ISP pe faʻafefea ona togafitia aʻu tulafono DMARC ma SPF faʻapea foʻi ma le mea e lafo ai soʻo se lipoti faʻafeiloaʻi. Ou te manaʻo i ISP e teena soʻo se feʻau e le pasi DKIM poʻo SPF, ma ou te manaʻo latou te lafo lipoti i lena tuatusi imeli.

  • Faailoga Faʻailo mo le Faʻailoaina o le Savali (BIMI) - o le faʻaopoopoga fou, e tuʻuina atu e le BIMI se auala mo ISP ma a latou imeli imeli e faʻaalia ai le logo o le faʻailoga i totonu o le imeli meli. O lo'o i ai uma se tulaga tatala fa'apea fo'i ma se fa'ailoga fa'ailoga mo Gmail lea e te mana'omia ai fo'i se tusi fa'ailoga fa'ailoga. O tusi pasi e fai si taugata o lea ou te le o faia i le taimi nei.

O loʻo i ai se fofo sili atu, e ui i lea, ma e faʻaaoga DKIMValidator. DKIMValidator e tu'uina atu ia te oe se tuatusi imeli e mafai ona e fa'aopoopo i lau lisi o talafou pe lafo mai i lau imeli ile ofisa...ma latou fa'aliliuina fa'amatalaga ulutala ile lipoti manaia:

Muamua, e faʻamaonia laʻu DMARC encryption ma DKIM saini e vaʻai pe pasi pe leai (e leai).
