TL; DR / Tseem ceeb Takeaways

• MX cov ntaub ntawv qhia rau lub ntiaj teb uas neeg rau zaub mov txais kev xa ntawv rau ib tug domain; temp mail providers taw tes rau ntau domains rau ib tug MX fleet.
• SMTP xa cov lus: lub hnab ntawv hais kom ua (MAIL FROM, RCPT TO) txawv ntawm qhov pom Los ntawm: header.
• Catch-tag nrho routing lees txais txhua qhov chaw hauv zos ua ntej @, ua kom tam sim ntawd, tsis muaj kev sau npe chaw nyob.
• Cov lus yog parsed, tsau tshuaj, thiab khaws cia luv luv (feem ntau nyob rau hauv lub cim xeeb) nrog ib tug nruj TTL (piv txwv li, ~ 24h).
• Pem hauv ntej-xaus kev xaiv tsa lossis kwj hloov tshiab kom lub inbox xav tias lub sijhawm tiag tiag.
• Domains tig los txo kev thaiv; OTP qeeb feem ntau yog vim throttling, lim dej, lossis tsis ua haujlwm ib ntus.
• Xaiv lub neej luv luv inboxes rau cov lej nrawm thiab chaw nyob rov siv tau thaum koj xav tau cov ntawv txais nyiaj lossis xa rov qab.

Nkag siab MX & SMTP

Tus txha caj qaum ntawm temp mail yog tus qauv email kav dej: DNS routing ntxiv rau ib qho yooj yim xa ntawv hloov kev sib tham.

MX piav qhia-meej.

Xa Ntawv Exchanger (MX) cov ntaub ntawv yog DNS nkag uas hais tias, "xa email rau tus sau no rau cov neeg rau zaub mov no." Txhua MX muaj tus lej nyiam; Cov neeg xa khoom sim tus lej qis tshaj plaws ua ntej thiab rov qab mus rau tom ntej yog tias xav tau. Cov chaw muab kev xa ntawv Temp feem ntau ua haujlwm ua ke ntawm cov domains taw tes rau tib lub MX fleet, yog li ntxiv lossis so haujlwm tsis hloov pauv lub raj xa dej tau txais.

SMTP tsis muaj lub jargon

Ib tug xa neeg rau zaub mov txuas thiab hais lus SMTP sequence: EHLO / HELO → MAIL LOS NTAWM → RCPT RAU → COV NTAUB NTAWV → TAWM. Ob cov ntsiab lus tseem ceeb ntawm no:

• Lub hnab ntawv (MAIL FROM, RCPT TO) yog dab tsi tus neeg rau zaub mov txoj kev rau-nws tsis yog tib yam li qhov pom Los ntawm: header hauv cov lus lub cev.
• Cov lej teb teeb meem: 2xx = xa tuaj; 4xx = ib ntus tsis ua hauj lwm (sender yuav tsum resim); 5xx = tas mus li tsis ua hauj lwm (bounce). Cov lej ib ntus pab txhawb rau OTP "lag", tshwj xeeb tshaj yog thaum cov neeg xa khoom throttle lossis receivers greylist.

Vim li cas nws tseem ceeb rau kev xa ntawv temp

Vim tias kaum ob lossis ntau pua tus domains txhua tus tsaws rau ntawm ib qho MX caj qaum, tus neeg zov me nyuam tuaj yeem siv cov kev tiv thaiv kev tsim txom zoo ib yam, tus nqi-txwv, thiab cov tswv yim scaling ntawm ntug thaum tseem khaws onboarding tam sim ntawd rau cov neeg siv pom qhov chaw tshiab.

(Koj yuav saib tau cov txheej txheem cej luam rau ib tug maj mam intro rau temp mail.)

Tsim Cov Chaw Nyob Pov Tseg

Qhov kev pabcuam tshem tawm kev sib txhuam los ntawm kev ua kom lub zos ib feem ntawm qhov chaw nyob pov tseg thiab tam sim ntawd.

Ntes-txhua qhov kev lees txais

Nyob rau hauv ib qho kev teeb tsa, tus neeg rau zaub mov tau txais kev teeb tsa los lees txais kev xa ntawv rau txhua qhov chaw hauv zos ua ntej @. Qhov ntawd txhais tau tias abc@, x1y2z3@ lossis ntawv xov xwm-promo@ txhua txoj hauv kev mus rau lub thawv xa ntawv siv tau. Tsis muaj kauj ruam sau npe ua ntej; thawj tus tau txais email tau zoo tsim lub thawv xa ntawv nkag nrog TTL tom qab qhov xwm txheej.

On-tus-yoov randomization

Web thiab app interfaces feem ntau qhia ib tug random alias rau nplooj ntawv load (piv txwv li, p7z3qk@domain.tld) los ua luam tam sim ntawd thiab txo kev sib tsoo. Lub kaw lus yuav hash cov tswv yim no lossis ntsev lawv nrog lub sijhawm / ntaus ntawv tokens rau qhov tshwj xeeb yam tsis muaj kev khaws cia cov ntaub ntawv tus kheej.

Yeem subaddressing

Qee lub tshuab txhawb nqa tus neeg siv + tag@domain.tld (aka ntxiv-chaw nyob) yog li koj tuaj yeem sau npe sau npe. Nws yooj yim, tab sis tsis universally honored-catch-tag nrho ntxiv randomized aliases yog ntau portable thoob plaws qhov chaw.

Thaum twg rov siv dua vs. hloov

Yog tias koj xav tau kev xa khoom ntawm cov ntawv txais nyiaj, xa rov qab, lossis rov qab los ntawm lo lus zais rov qab tom qab, siv qhov chaw nyob rov qab siv tau khi rau lub cim ntiag tug. Thaum koj tsuas xav tau tus lej ib zaug, xaiv lub inbox luv luv uas koj yuav muab pov tseg tom qab siv. Koj tuaj yeem rov qab siv tib qhov chaw nyob temp nrog lub token thaum tsim nyog los ntawm Rov Siv Koj Lub Sij Hawm Xa Ntawv Chaw Nyob, thiab xaiv 10-feeb inbox thaum koj xav tau tus cwj pwm ceev, ephemeral (10 feeb Xa Ntawv).

Parse thiab Khaws Cov Lus

Tom qab lub scenes, tus neeg rau zaub mov tsau tshuaj thiab normalizes mail ua ntej luv luv-lub sij hawm cia.

Parsing cov lus

Thaum tau txais, qhov kev pabcuam validates cov kev cai ntawm tus neeg tau txais kev pab (ntes-tag nrho, quotas, tus nqi-txwv) thiab parses cov lus:

• Headers & MIME: Extract subject, sender, thiab qhov chaw (tiaj ntawv / HTML).
• Kev Nyab Xeeb: Sawb cov ntsiab lus nquag; proxy lossis thaiv cov duab tej thaj chaw deb los cuam tshuam kev taug qab pixels.
• Normalization: Hloov ua lwm yam quirky encodings, flatten zes multiparts, thiab tswj kom muaj ib qho zoo ib yam HTML subset rau zaub.

Transient cia los ntawm kev tsim qauv

Ntau tus neeg zov me nyuam siv cov ntaub ntawv ceev ceev, hauv lub cim xeeb cov ntaub ntawv khaws cia rau cov lus kub thiab yeem cov khw muag khoom ruaj khov rau kev rov qab los ua rau lub inbox xav tias tam sim ntawd. Cov yuam sij thawj index feem ntau yog tus neeg tau txais alias thiab lub sij hawm. Txhua cov lus yog tagged nrog TTL, yog li nws cia li tas sijhawm.

Vim li cas cov khw muag khoom nco ci

Ib lub khw muag khoom hauv lub cim xeeb nrog haiv neeg tseem ceeb tas sij hawm phim cov khoom cog tseg: tsis muaj kev khaws cia mus sij hawm ntev, kev tshem tawm ncaj qha thiab kev twv ua ntej hauv qab OTP loads tawg. Kab rov tav sharding-los ntawm sau los yog hash ntawm lub zos-ib feem-cia lub kaw lus nplai tsis muaj centralized bottlenecks.

Ib daim ntawv ceeb toom ntawm cov ntawv txuas

Txhawm rau txo kev tsim txom thiab kev pheej hmoo, tej zaum yuav raug thaiv cov ntawv txuas ncaj qha lossis txwv; feem ntau ntawm lub sijhawm xa ntawv siv cov ntaub ntawv (cov lej thiab kev lees paub) yog cov ntawv nyeem lossis HTML me me xijpeem. Txoj cai no khaws cia ceev thiab kev nyab xeeb rau feem ntau ntawm cov neeg siv.

Qhia Lub Inbox Hauv Lub Sijhawm Tiag

Qhov ntawd "tam sim ntawd" xav los ntawm cov neeg siv khoom ntse hloov tshiab, tsis yog khoov email cov cai.

Ob qho qauv hloov tshiab feem ntau

Ncua sij hawm / ntev-pov npav: Tus neeg tau txais kev pab nug tus neeg rau zaub mov txhua N vib nas this rau kev xa ntawv tshiab.

Pros: yooj yim los siv, CDN / cache-phooj ywg.

Qhov zoo tshaj plaws rau: Cov chaw sib yuag, tsheb me me, ua siab ntev rau 1–5s qeeb.

WebSocket / EventSource (neeg rau zaub mov laub): Tus neeg rau zaub mov ceeb toom rau tus neeg siv khoom thaum cov lus tuaj txog.

Pros: qis dua latency, tsawg dua redundant thov.

Qhov zoo tshaj plaws rau: high-traffic apps, txawb, los yog thaum nyob ze-real-time UX tseem ceeb.

Responsive UI qauv

Siv qhov pom "tos cov lus tshiab..." qhov chaw, qhia lub sijhawm tshiab kawg, thiab debounce phau ntawv rov ua dua tshiab kom tsis txhob hammering. Khaws lub qhov (socket) lub teeb yuag rau kev siv mobile thiab cia li nres thaum lub app yog keeb kwm yav dhau. (Yog hais tias koj nyiam haiv neeg apps, muaj ib tug txheej txheem cej luam ntawm temp mail rau mobile uas npog Android thiab iOS muaj peev xwm: Zoo tshaj plaws Temp Xa Ntawv App rau hauv & iPhone.)

Deliverability kev muaj tiag xyuas

Txawm hais tias muaj kev thawb, kev xa ntawv tshiab tsuas yog tshwm sim tom qab SMTP kev xa khoom tiav. Nyob rau hauv cov ntaub ntawv ntug, ib ntus 4xx teb, greylisting, los yog sender throttles ntxiv vib nas this rau feeb ntawm qeeb.

Cov Ntaub Ntawv Tas Sij Hawm Txhim Kho

Nws pib-rhuav tshem yog ib tug ceev ntiag tug feature thiab ib tug kev ua tau zoo cuab yeej.

TTL semantics

Txhua cov lus (thiab qee zaum lub plhaub xa ntawv) nqa ib qho kev suav npe-feem ntau nyob ib ncig ntawm 24 teev-tom qab cov ntsiab lus raug tshem tawm irreversibly. UI yuav tsum sib txuas lus qhov no kom meej kom cov neeg siv tuaj yeem luam cov lej tseem ceeb lossis cov ntawv txais nyiaj thaum lawv muaj.

Ntxuav cov neeg kho tshuab

Muaj ob txoj kev sib ntxiv:

• Haiv neeg tseem ceeb tas sij hawm: Cia lub khw hauv lub cim xeeb rho tawm cov yuam sij cia li ntawm TTL.
• Keeb kwm yav dhau los sweepers: Cron cov hauj lwm luam theej duab thib ob khw muag khoom thiab ntxuav txhua yam dhau los tsim nyog.

Dab tsi cov neeg siv yuav tsum tau cia siab

Lub thawv xa ntawv temp yog lub qhov rais, tsis yog lub vault. Yog tias koj xav tau cov ntaub ntawv, siv qhov chaw nyob rov qab tiv thaiv los ntawm lub token kom rov qab los tom qab thiab rub tib lub inbox. Nyob rau tib lub sijhawm, cov lus tseem hwm txoj cai khaws cia ntawm qhov kev pabcuam.

(Rau ib tug tswv yim txheej txheem cej luam ntawm luv luv-lub neej tus cwj pwm, lub 10-feeb inbox piav qhia yog pab tau.)

Tig Domains Ntse

Kev sib hloov txo cov blocks los ntawm kev kis lub koob npe nrov thiab so haujlwm "hlawv" domains.

Vim li cas cov thaiv tshwm sim

Qee lub vev xaib chij cov chaw pov tseg los tiv thaiv kev dag ntxias lossis kev tsim txom daim coupon. Qhov ntawd tuaj yeem ua rau muaj qhov tsis tseeb, ntes cov neeg siv kev ceev ntiag tug nrog cov kev xav tau raug cai.

Yuav ua li cas kev sib hloov pab

Cov chaw zov me nyuam tuav cov pas dej ntawm domains. Cov tswv yim tig mus rau cov chaw tshiab; cov teeb liab zoo li nyuaj bounces, kev tsis txaus siab spikes, lossis phau ntawv ceeb toom ua rau ib qho chaw nres lossis so haujlwm. Lub MX fleet nyob zoo li qub; tsuas yog cov npe hloov, uas ua rau kev tsim kho vaj tse yooj yim.

Yuav ua li cas yog tias thaiv

Yog tias ib lub xaib tsis lees txais koj qhov chaw nyob, hloov mus rau lwm tus sau thiab thov OTP dua tom qab tos luv luv. Yog tias koj xav tau kev nkag mus tas li rau cov ntawv txais nyiaj lossis xa rov qab, nyiam qhov chaw nyob rov qab siv tau khi rau koj tus kheej token.

Daim ntawv ceeb toom infrastructure

Ntau tus neeg muab kev pabcuam tso lawv cov MX fleet tom qab muaj zog, thoob ntiaj teb kev tsim kho kom ncav cuag zoo dua thiab ua haujlwm-qhov no pab cov ntawv tuaj txog sai sai tsis hais cov neeg xa khoom nyob qhov twg (saib qhov laj thawj rau kev siv cov neeg xa ntawv thoob ntiaj teb hauv Vim li cas tmailor.com Siv Google Cov Neeg Rau Zaub Mov los Ua Cov Email Tuaj?).

Daws teeb meem OTP Kev Xa Khoom

Feem ntau hiccups yog piav qhia-thiab kho tau-nrog ob peb qhov tseeb txav.

Cov laj thawj feem ntau

• Tus neeg xa khoom throttles lossis staggers OTP lus; Koj qhov kev thov yog queued.
• Qhov tau txais ntug siv greylisting; Tus neeg xa ntawv yuav tsum rov sim dua tom qab ncua sijhawm luv luv.
• Lub xaib thaiv tus sau koj siv; Cov lus yeej tsis tau xa.
• Lub mistyped hauv zos ib feem yog ib qho yooj yim mus nco thaum luam nyob rau hauv mobile.

Dab tsi los sim tom ntej

• Rov xa dua tom qab tos ib nyuag (piv txwv li, 60–90 vib nas this).
• Thov cia li mus tom ntej thiab tig tus sau thiab sim dua; Xaiv ib tug alias tsis muaj cim los yog txawv txawv Unicode.
• Nyob twj ywm ntawm tib nplooj ntawv / app thaum tos; Qee cov kev pabcuam invalidate cov lej yog tias koj taug kev deb.
• Rau cov kev xav tau mus sij hawm ntev (cov ntawv txais nyiaj, taug qab), txav mus rau qhov chaw nyob rov qab siv tau los ntawm koj lub token.

(Yog tias koj tshiab rau kev xa ntawv temp, FAQ nplooj ntawv sau cov lus teb luv luv rau cov teeb meem ntau zaus: Cov Lus Nquag Nug Txog Temp Xa Ntawv.)

Siv Cov Ntaub Ntawv thiab Cov Txwv

Temp mail yog qhov zoo tshaj plaws rau kev ceev ntiag tug thiab kev sib txhuam tsawg-tsis yog raws li ib tug tas mus li archive.

Zoo haum

• Ib zaug kos npe, kev sim siab, ntawv xov xwm thiab rub tawm rooj vag.
• Kev txheeb xyuas qhov twg koj tsis xav tso koj qhov chaw nyob tseem ceeb.
• Kev sim ntws raws li tus tsim tawm lossis QA yam tsis muaj kev muab cov inboxes tiag tiag.

Ceev faj

• Tus account rov qab yuav tsum tau ua (qee qhov chaw xav tau email ruaj khov ntawm cov ntaub ntawv).
• Cov ntawv txais nyiaj / xa rov qab logistics-siv lub inbox rov qab siv tau yog tias koj xav tias cov lus yav tom ntej.
• Cov vev xaib uas thaiv cov chaw pov tseg; npaj kom tig los yog xaiv lwm txoj kev ntws yog tias xav tau.

Yuav ua li cas tag nrho cov dej ntws haum ua ke

Ntawm no yog lub neej voj voog los ntawm alias mus rau deletion.

1. Koj lees txais los yog luam ib tug tswv yim alias.
2. Tus xa mus saib MX rau tus sau ntawd thiab txuas rau tus neeg zov me nyuam MX.
3. SMTP tuav tes ua tiav; Tus neeg rau zaub mov lees txais cov lus nyob rau hauv catch-tag nrho cov cai.
4. Lub kaw lus parses thiab tsau cov ntsiab lus; trackers yog neutered; tej zaum yuav thaiv.
5. Ib qho TTL tau teeb tsa; Cov lus yog khaws cia rau hauv lub cim xeeb ceev rau kev nyeem ntawv sai.
6. Lub vev xaib / app pov npav lossis mloog cov ntawv xa ntawv tshiab thiab hloov kho koj lub inbox saib.
7. Tom qab lub qhov rais TTL, keeb kwm yav dhau cov hauj lwm los yog haiv neeg expiry rho tawm cov ntsiab lus.

Ceev Yuav Ua Li Cas: Xaiv Hom Chaw Nyob Txoj Cai

Ob kauj ruam kom tsis txhob mob taub hau tom qab.

Kauj ruam 1: Txiav txim siab lub hom phiaj

Yog tias koj xav tau tus lej, siv lub npe luv luv uas koj yuav muab pov tseg. Yog tias koj cia siab tias cov ntawv txais nyiaj, taug qab lossis lo lus zais rov ua dua, xaiv qhov chaw nyob rov qab siv tau khi rau lub cim ntiag tug.

Kauj ruam 2: Khaws nws yooj yim

Xaiv ib tug alias nrog yooj yim ASCII tsiaj ntawv/xov tooj kom tsis txhob xa cov kab. Yog tias ib lub xaib thaiv tus sau, hloov domains thiab rov sim cov cai tom qab lub sijhawm luv luv.

FAQ (nyeem ntawv-ntsej muag)

Puas yog MX qhov tseem ceeb ua rau kev xa khoom sai dua?

Lawv ua kom ntseeg tau ntau dua li qhov nrawm: cov neeg xa khoom sim tus lej qis tshaj plaws ua ntej thiab poob rov qab yog tias xav tau.

Vim li cas qee qhov chaw thaiv cov chaw nyob pov tseg?

Txhawm rau txwv kev tsim txom thiab kev siv daim coupon tsis raug. Hmoov tsis zoo, qhov ntawd tseem tuaj yeem thaiv cov neeg siv kev ceev ntiag tug.

Puas yog ntes-txhua yam muaj kev nyab xeeb?

Nws muaj kev nyab xeeb nrog kev tswj hwm kev tsim txom nruj, tus nqi-txwv, thiab tuav luv luv. Lub hom phiaj yog txhawm rau txo cov ntaub ntawv ntiag tug thiab tsis txhob khaws cov ntawv xa mus ib txhis.

Vim li cas kuv OTP tsis tuaj txog?

Cov lus teb rau neeg rau zaub mov ib ntus, xa khoom throttles, lossis ib qho chaw thaiv yog qhov qub. Koj puas tuaj yeem xa rov qab tom qab tos luv luv thiab xav txog qhov chaw tshiab?

Koj puas xav tias kuv tuaj yeem siv tib qhov chaw nyob temp?

Yog lawm-siv lub cim tiv thaiv rov qab chaw nyob rov qab mus rau tib lub inbox tsis pub dhau txoj cai txwv.
