DMARC Nedir, Neden \u00d6nemlidir?<\/h2>\n

DMARC, yani “Domain-based Message Authentication, Reporting & Conformance<\/strong>“, e-posta<\/a> g\u00fcvenli\u011fini sa\u011flamak i\u00e7in kullan\u0131lan bir do\u011frulama protokol\u00fcd\u00fcr.

K\u0131sacas\u0131 DMARC, alan ad\u0131n\u0131z\u0131 taklit etmeye \u00e7al\u0131\u015fan k\u00f6t\u00fc niyetli ki\u015filerin \u00f6n\u00fcne ge\u00e7er.

Bu da m\u00fc\u015fterilerinizin g\u00fcvenini kaybetmenize, hatta marka imaj\u0131n\u0131z\u0131n zarar g\u00f6rmesine neden olabilir.<\/p>\n
