Chofoza okuthi "vumela" inketho yokunika amandla i-DomainKeys futhi Khubaza ukuyivimbela.
Ukusetha i-SPF
- U-SPF ukhohlwa igama lesizinda sakho njengomthumeli, ngaleyo ndlela uvimbela abagaxekile ukuba bathumele ama-imeyili. Kulesi sici, amakheli e-IP aqala ukufakwa ohlwini. Lokhu kugunyaza kuphela isethi ethile yamakhompiyutha ukuthumela ama-imeyili kusuka egameni lesizinda.

phika umlayezo = "Akulungile kusuka kukheli <$ {sender_address}>. Sicela usebenzise <$ {authenticated_id}> esikhundleni" ukuqinisekiswa = *! isimo = $ {uma i-match_address {$ {sender_address}} {$ authenticated_id}}
} Qaphela: Sicela ususe izikhala ezimhlophe - kwadingeka ngibange ngamabomu ngoba kungenjalo, kungaba ikhodi esebenzayo, futhi ngeke kushicilelwe njengombhalo ocacile kuleli khasi lewebhu.
Izilungiselelo ezithuthukile ku-canel
Izilungiselelo ezithuthukile ku- canel zinikeza izindlela ezahlukene zokuthuthukisa inqubo yokugunyaza.
Okulandelayo yizinketho ezivamile ezitholakalayo onawo:
- Ukwengeza amasbinza kusizinda samanje kuvunyelwe ngokuzenzakalelayo. Zingasuswa noma zengezwe ngezinkinobho ezifanele.
