Momwe Mungakhazikitsire Kutsimikizika kwa Imelo ndi Microsoft Office (SPF, DKIM, DMARC)

Microsoft Office 365 Email Authentication - SPF, DKIM, DMARC

Tikuwona zovuta zambiri zobweretsera makasitomala masiku ano ndipo makampani ambiri alibe zofunikira kutsimikizika kwa imelo khazikitsani ndi ma imelo awo akuofesi komanso opereka maimelo otsatsa. Zaposachedwa kwambiri zinali kampani ya ecommerce yomwe tikugwira nayo ntchito yomwe imatumiza mauthenga awo othandizira kuchokera ku Microsoft Exchange Server.

Izi ndizofunikira chifukwa maimelo othandizira makasitomala a kasitomala akugwiritsa ntchito masinthidwe amakalatawa kenako amadutsidwa kudzera munjira yawo yothandizira. Chifukwa chake, ndikofunikira kuti tikhazikitse Kutsimikizika kwa Imelo kuti maimelowo asakanidwe mosadziwa.

Mukakhazikitsa Microsoft Office pa domain yanu, Microsoft imakhala ndi kuphatikiza kwabwino ndi maseva ambiri a Domain Registration komwe amangokhazikitsa masinthidwe onse ofunikira (MX) zolemba komanso Sender Policy Framework (SPF) lembani imelo yanu ya Office. Mbiri ya SPF yokhala ndi Microsoft yotumiza imelo yakuofesi yanu ndi zolemba (TXT) mu registrar yanu ya domain yomwe ikuwoneka motere:

v=spf1 include:spf.protection.outlook.com -all

SPF ndiukadaulo wakale, komabe, kutsimikizika kwa imelo kwapita patsogolo ndi Domain-based Message Authentication, Reporting and Conformance (Chithunzi cha DMARC) ukadaulo komwe sikungasokoneze dera lanu ndi imelo sipammer. DMARC imapereka njira yokhazikitsira kukhwimitsa komwe mukufuna opereka chithandizo pa intaneti (ISP) kuti atsimikizire zomwe mwatumiza ndikukupatsani kiyi yapagulu (RSA) kuti mutsimikizire domeni yanu ndi wopereka chithandizo, apa, Microsoft.

Njira zokhazikitsira DKIM mu Office 365

Ngakhale ma ISP ambiri amakonda Malo Ogwirira Ntchito a Google kukupatsirani zolemba ziwiri za TXT kuti mukhazikitse, Microsoft imachita mosiyana pang'ono. Nthawi zambiri amakupatsirani zolemba za 2 CNAME pomwe kutsimikizika kulikonse kumatumizidwa ku maseva awo kuti awonedwe ndikutsimikizira. Njirayi ikukhala yofala kwambiri m'makampani… makamaka ndi opereka maimelo ndi othandizira a DMARC-monga-ntchito.

  1. Sindikizani zolemba ziwiri za CNAME:

CNAME: selector1._domainkey 
VALUE: selector1-{your sending domain}._domainkey.{your office subdomain}.onmicrosoft.com
TTL: 3600

CNAME: selector2._domainkey
VALUE: selector2-{your sending domain}._domainkey.{your office subdomain}.onmicrosoft.com

Zachidziwikire, muyenera kusintha dera lanu lotumizira ndi ofesi yanu motsatana ndi chitsanzo pamwambapa.

  1. Mukapanga makiyi anu a DKIM, muyenera kuyatsa Sainani mauthenga a domeniyi ndi siginecha za DKIM. Cholemba chimodzi pa izi ndikuti zingatenge maola kapena masiku kuti izi zitsimikizike popeza zolemba za domain zimasungidwa.
  2. Mukasinthidwa, mutha yendetsani mayeso anu a DKIM kuonetsetsa kuti zikugwira ntchito moyenera.
