Hopu-Katoa & Ingoakē Matapōkere: He aha te Mēra Rangitahi e Rongo Inamata

I runga i te mata, he iti noa iho: patohia tētahi wāhitau, ā, ka tae mai te mēra. I ngā tikanga tūturu, he kōwhiringa pūkaha taua whakaaro inamata: whakaae i te tuatahi, whakatau horopaki ā muri ake. Ka wetewete tēnei whakamārama me pēhea te tango i te whakatipuranga ingoakē matapōkere me te whakatipuranga ingoakē matapōkere i a ia e whakahaere ana i te tūkinotanga. Mō ngā pūkaha whānui ake puta noa i te ararere MX, ngā huringa ora pouakaroto, me te whakamahi anō i te tohu, tirohia te pou Hoahoa Īmēra Rangitahi: Mutunga-ki-te-Mutunga (A–Z).

TL; DR / Key Takeaways

• Mā te hopu-katoa e whakaae ai tētahi rohe ki tētahi wāhanga-paetata i mua i te @, ka whakakore i te hanganga tōmua o ngā pouaka mēra.
• Ka tāruatia ngā ingoakē matapōkere i roto i te pato, ka whakaiti i ngā tūtukitanga, me te karo i ngā tauira matapae.
• He mea nui ngā mana: ko ngā tepe mokatere, ngā tohatohatanga, ngā heuristics, me ngā TTL poto e pupuri ana i te tere me te kore ngangau.
• Whakamahia he pouakaroto ka taea te whakamahi anō mō ngā rihīti/whakahoki me ngā tautuhi anō; whakamahia te wā poto mō te OTP wā kotahi.
• Mō ia kaupapahere, ka ākiritia ngā āpitihanga; Kua horoia te HTML; Ka pau aunoatia ngā tinana īmēra.

Hopu-Katoa E Mahi Ana

Whakaitia ngā pāwhiri mā te tīpoka hihiri i ngā karere waihanga-tōmua me te mahere hihiri ki tētahi horopaki pouakamēra.

He pēhea te mahi a te hopu-katoa

Ka whakaae tētahi rohe hopu-katoa ki tētahi wāhanga paetata (mauī o te @ ) me te whakatau i te tukunga i te tapa. Kua whakamanatia te pūhera SMTP (RCPT TO) ki te kaupapahere rohe, kaua ki tētahi haupae pouaka mēra tīariari kē. E ai ki ngā ture me te āhua kaiwhakamahi, ka ararere te pūnaha i te karere ki tētahi horopaki pouakamēra tērā pea he rangirua (poto), he tohu rānei (ka taea te whakamahi anō).

Ka mīharo, ka takahuri tēnei i te rere pūnoa. Ehara i te "waihanga → manatoko → whiwhi," ko te "whiwhi → tautapa → whakaaturanga." Tērā tētahi hopu: me here koe i te whakaaetanga ki ngā tepe rahi me te tāhuahua haumaru.

Mahere: Horopaki → Rohe → Pouakamēra

• Kaupapahere rohe: catch_all = takahuri pono i te whakaaetanga; Ka whakaaetia e ngā rārangi ārai ngā whakairo pū.
• Kaiwhakahaere: ka tirotirohia e te pouara ngā wāhanga paetata, ngā pane, me ngā rongo IP, kātahi ka kōwhiri i tētahi horopaki.
• Horopaki pouakamēra: ephemeral, ka taea rānei te whakamahi anō; ka tautuhia e ngā horopaki te TTL (hei tauira, te matapihi whakaatu 24h), ngā tohatohatanga, me ngā whakaritenga maimai.

Ngā Pai me ngā Kino

Ngā painga

• Te whakaurunga hipanga-kore; Ka whai wāhi ā-rohe ināianei tonu.
• Whakahekea te whāngai mō te OTP me ngā waitohu; iti ake ngā puka kua mahue.
• He pai te mahi ki ngā taketake mēra rangitahi me te takahuringa rohe.

Ngā kino

• Ētahi atu mēra kāore i te hiahiatia ki te kore e tiakina.
• He tiaki anō mō te tāhuahua: horoi i te HTML me ngā pūaroturuki paraka.
• E hiahiatia ana ngā mana tūkino pakari hei karo i te marara whakamuri me te moumou rauemi.

Kaupapahere Whakaaetanga (Haumaru Taunoa)

• Rahi mōrahi: ākiritia ngā tinana/āpitihanga nui i SMTP; Whakaū i te mōrahi paita karere mō ia horopaki.
• Ngā āpitihanga: ākiritia hāngai (whiwhi-anake, kāore he āpitihanga) hei whakaiti i te mōrea me te kawenga rokiroki.
• Tāhuahua: horoi i te HTML; ngā atahanga takawaenga; Ngā pūaroturuki tīhore
• Mōnehu: whakaatu matapihi ~24h mō ngā mēra kua whiwhia i roto i ngā horopaki rangirua; muna i te paunga.

Hanga Ingoakē Matapōkere Atamai

Waihangatia inamata tētahi ingoakē, tāruatia i roto i te nekehanga kotahi, me te pupuri i ngā tauira uaua ki te matapae.

He pēhea te waihanga ingoakē

Ina pato te kaiwhakamahi i te Whakaputa, ka hangaia e te pūnaha tētahi wāhanga paetata mā te whakamahi i te entropy mai i ngā tohu wā me ngā tohu pūrere. Ehara i te mea ōrite ngā pūhiko katoa. Ngā mea kaha:

• Whakamahia ngā whāranu base62/hex me ngā taki tītaha hei karo i ngā tauira pānui pēnei i te aaa111.
• Whakaū i te roanga mōkito (hei tauira, 12+ pūāhua) i a koe e rata ana ki te puka.
• Hoatu ngā ture huinga pūāhua hei karo i ngā āhuatanga pūtaurima mēra (. raupapatanga, whai muri -, aha atu).

Ngā Taki Tūtuki me te TTL

• Tūtukitanga: ka kitea e tētahi tātari Bloom tere + huinga hash te whakamahinga o mua; whakatupu anō tae noa ki te ahurei.
• TTL: ka riro i ngā ingoakē oranga poto tētahi TTL whakaatu (hei tauira, ~24h i muri i te rihīti); Ka herea ngā ingoakē ka taea te whakamahi anō ki tētahi maimai, ā, ka taea te whakatuwhera anō ā muri ake.

UX e whakahau ana i te whakamahinga tika

• Tārua pato-kotahi me te ingoakē ari.
• Whakatupuria anōtia te pātene inā whakakāhore tētahi pae i tētahi tauira.
• Tohu TTL hei tautuhi i ngā tūmanako mō ngā pouakaroto poto.
• Ko ngā whakatūpato mō ngā pūāhua rerekē, kāore ētahi pae ruarua e whakaae.
• Hono-whakawhiti ki ngā pouakaroto kāhua-10 meneti ina taea te whakawātea.

Wāhitauroto (kaiwhakamahi+tūtohu)

He whaitake te wāhitau tāpiri (kaiwhakamahi+tag@domain) mō te kōmaka, engari kāore e tautokona e ngā paetukutuku. I runga i te toenga, he tino pai te wāhitau roto mō ngā rohe whaiaro; Mō ngā waitohu kore-whāngai i te tauine, ka nui ake ngā whakamanatanga o ngā ingoakē matapōkere i tētahi rohe hopu-katoa. Mō te māramatanga o te kaiwhakawhanake, ka whakataurite poto mātou ki te ararere hopu-katoa i roto i te FAQ i raro nei.

Me Pēhea Tere: Hanga me te Whakamahi i tētahi Ingoakē

Hipanga 1: Waihangatia he ingoakē

Pato Whakanao hei whiwhi i tētahi wāhanga-paetata matapōkere; Tāruatia mā te pato kotahi. Ki te whakakāhore tētahi paetukutuku, pato Whakatupu anō mō tētahi tauira hōu.

Hipanga 2: Kōwhiria te horopaki tika

Whakamahia te roa-poto mō ngā waehere wā-kotahi; Whakamahia ngā wāhitau ka taea te whakamahi anō ina hiahia koe ki ngā rihīti, whakahokinga, tautuhi kupuhipa anō rānei ā muri ake.

Whakahaere i te Tūkino me te Kore Pōturi

Kia tere tonu te wheako i a koe e whakawhāiti ana i te tūkino me ngā taraiwa waka rerekē.

Ngā Tepenga Mokatere me ngā Tohatoha

• Ngā throttles ia-IP & ia-ingoakē: ngā tepe pahū mō ngā pahū OTP; pūmatua tautokona hei aukati i te waru.
• Te tohatoha rohe: whakakapia ngā tukunga taki-rohe mō ia kaiwhakamahi/wātū hei aukati i tētahi pae kia kore ai e waipuke i tētahi pouakaroto.
• Hanga urupare: rahua tere i te SMTP mō ngā kaituku kua rāhuitia hei tiaki i te CPU me te hōkaiipurangi.

Ngā Tohu Heuristics me ngā Tohu Anomaly

• N-gram & pattern risk: kara i ngā kuhimua tukurua (hei tauira, hoko, manatoko) e tohu ana i te whakamahinga hē hōtuhi.
• Te rongo o te kaituku: paunatia te rDNS, SPF/DMARC presence, me ngā putanga o mua
• [Suy luận: ka whakapai ake ngā tohu paheko i te whakamātautau, engari he rerekē ngā taumahatanga tūturu i te kaiwhakarato].
• Te takahuringa rohe ā-pae: tītaka puta noa i ngā rohe kia kore ai e kati, me te pupuri i te hononga ina hiahiatia, e ai ki te kōrerorero i roto i te pou.

TTL Poto me te Rokiroki Mōkito

• Mā ngā matapihi whakaatu poto e whakaiti ai i te raraunga me te whakaiti i te uara tūkino.
• Kāore he āpitihanga; Ka whakahekea e HTML te mata mōrearea me ngā utu tāhuahua.
• Mukua i te paunga: tangohia ngā tinana karere ā muri i te mutunga o te matapihi whakaatu.

Mō te ngāwari pūkoro, me whakaaro ngā kaiwhakamahi e waitohu ana i te wā e haere ana ki ngā mēra rangitahi i te Android me te iOS kia tere ake ai te urunga me ngā whakamōhiotanga.

Kōwhiri Ka Taea te Whakamahi Anō me te Oranga-Poto

Whakataurite i te momo pouakaroto ki tō tauari: hononga mō ngā rihīti, whakawātea mō ngā waehere.

Tauritenga Tauari

Parenga Maimai (Ka Taea te Whakamahi Anō)

Ka herea ngā wāhitau ka taea te whakamahi anō ki tētahi maimai āheitanga. Ka whakatuwhera anō te maimai i te pouakamēra ōrite ā muri ake me te kore whakaatu i te tuakiri whaiaro. Ka ngaro te maimai, ā, kāore e taea te whakaora i te pouaka mēra. Ko te take, ko taua rohenga mārō te mea e pare ana i te ingoamuna i te tauine.

Mō ngā tauhou, ka tukuna e te whārangi tirohanga whānui mēra rangitahi he tohutohu tere me ngā hononga ki ngā FAQ.

Whakamutunga

Ko te raina raro ko tēnei: ko te whakaaetanga hopu-katoa me te whakatipuranga ingoakē atamai e tango ana i te whāngai tatūnga. I taua wā, ka noho tere, kia haumaru hoki te pūnaha. Kōwhiria he pouakaroto oranga-poto ina hiahia koe ki te ngaro; Kōwhiria he wāhitau ka taea te whakamahi anō ina hiahia koe ki tētahi makatea pepa. Hei whakaharatau, ka tiakina e taua whakataunga ngāwari ngā ānini ā muri ake.
