Vazhinji vashandisi, vakatarisana nechido chekugadzirisa izvi kana kuti mutengi wetsamba, anobvunzwa kuti: "Chii chinonzi email protocol". Chokwadi, ku "simba" chirongwa chakadai kuti chishande zvakanaka, uyezve zvakagadzikana kuti unzwisise kuti ndechipi chimwe chezvisarudzo zviripo zvinofanirwa kusarudzwa, uye chii musiyano kubva kune vamwe vese. Izvo ndezve mapepa epositari, iyo nheyo yebasa ravo uye chiyero chekushandisa, pamwe nezvimwewo zvimwe zvinwiwa zvichaudzwa munyaya ino.
Email Protocols
Pakakwana, pane matatu anowanzo kugamuchirwa zviyero zvinoshandiswa kuchinjanisa maemail (kutumira uye kuagamuchira) - ichi chiri imap, pop3 uye smtp. Pachine http, iyo inowanzonzi webhu-mail, asi haina hukama hwakananga kune yedu yanhasi yemazuva ano. Pazasi uchafunga mune zvimwe zvakadzama imwe neimwe yeiyo protocols, inofunga hunhu hwavo uye misiyano ingangoitika, asi tisati tapa tsananguro yezita iro pacharo.
Iyo email protocol, kana iwe ukataura mutauro wakareruka uye unonzwisisika - izvi zvinonyatsonzwisisa
SMTP (yakapusa tsamba yekuendesa protocol)
Rakareruka tsamba kuendesa protocol - Aya ndiwo mafambiro akazara SMTP anoshandurwa uye akashongedzwa. Chiyero ichi chinoshandiswa zvakanyanya kuendesa e-mail muTCP / IP network (zvakananga kuendesa kunze tsamba yeTCP 25). Kune zvakare zvakanyanya "mutsva" mutsva - iyo ESMTP kuwedzera (yakawedzerwa SMTP) yakatorwa muna2008, kunyangwe isina kuparadzaniswa kubva kune yakapfava tsamba yekutumira tsamba.
Iyo SMTP Protocol inoshandiswa nemavara maseva uye vamiririri vekutumira uye kugamuchira tsamba, asi zvinoshandiswa-zvevaterisi-vatengi-vatengesi-kutumira maemail kune server yavo inotevera.
Zvakawanda zvekushandisa, zvinosanganisira kuzivikanwa moziderbird, iyo bat !, Microsoft Outlook, shandisa chero pop, kana imap, iyo ichakurukurwa gare gare. Mune ino kesi, protocol protocol inogona kushandisa protocol yekuwana iyo mushandisi account pane yayo sevha kuti iwane mukana wekushandiswa kweserver neyakawana
Onawo: Dambudziko Rakagadzirisa mavara neemail
Post3 (post office protocol vhezheni 3)
Iyo post office protocol yeshanduro yechitatu (yakashandurwa kubva kuChirungu) iyo application-level - TCP / IP. Zvakananga mubasa rayo pop3 inoshandisa chiteshi pahuwandu 110, zvisinei, 995 inoshandiswa neSSL / TLS yekubatanidza.
Sezvataurwa pamusoro apa, iyi email protocol (pamwe nemumiriri unotevera wetsananguro yedu) inonyanya kuwanzoshandiswa kusvika zvakananga kudzosera tsamba. Kwete zvishoma, izvi zvinoruramiswa nenyaya yekuti imap, pamwe chete neIMAS, haina kungotsigirwa nezvirongwa zvepashure pezvirongwa zvakakodzera - gmail, Yahoo !, Hotmail, etc.
ONA: Iyo mwero mumunda ndiyo yechitatu vhezheni yeiyi protocol. Yokutanga uye yechipiri imwe kune iyo (pop, pop2, zvichiteerana), inoonekwa seyakagwinya.
Verenga zvakare: Gmail mail setup mune yekutumira mutengi
IMap (Internet meseji yekuwana protocol)
Ichi chiitiko chekushandisa-chikamu chemufananidzo wakashandiswa kuwana tsamba yemagetsi. Sezvo zviyero zvevakuru pamusoro, iyo IMAP inoenderana neTCP kutakura protocol, uye kuita mabasa akagoverwa, port 143 (kana 993 yeSSL / TLS yekubatanidza) inoshandiswa).
Chaizvoizvo, ndiyo internet meseji yekuwana protocol iyo inopa mikana yakakura yekushanda nemavara uye zvakananga nemabhokisi epositi akaiswa pane yepakati server. Chishandiso chevatengi chinoshandisa iyi protocol kuti basa rayo rashandiswe zvakakwana kune zvemagetsi zvekunyorerana sekunge kwete pane server, asi pane komputa yemushandisi.
IMAP inokutendera kuti uite zvese zvinodiwa zviito nemavara uye dhirowa (dhirowa) zvakananga pc pasina kudiwa kwekugara uchitumira kune server yakarongedzwa mafaera uye zvinyorwa zvemukati uye kumashure kwavari. Iyo pop3 inotariswa pamusoro, sezvo isu takatosarudzwa, zvinoshanda zvakasiyana, "kusimbisa" data rinodiwa kana rakabatana.
Onawo: Kugadzirisa matambudziko nekutumira maemail
Http.
Sezvataurwa pakutanga kwekutanga kwechinyorwa, http is a protocol iyo haina kuitirwa kutaurirana neemail. Panguva imwecheteyo, inogona kushandiswa kuwana iyo bhokisi retsamba, yekudhirowa (asi isiri kutumira) uye kugamuchira mavara emagetsi. Ndokunge, iyo chete chikamu chemabasa emabasa epositi akakurukurirana pamusoro apa. Uye zvakadaro, kunyangwe panguva imwe chete, zvinowanzonzi Webmail. Zvichida chimwe chikamu mune izvi chakaridzwa neiyo kamwe basa rinozivikanwa hotmail, rinoshandisa http.Sarudza email protocol
Saka, azvijaira iwe nemumwe weumwe neumwe weripo protocols iripo, tinogona kuchinjisa zvakachengeteka kune sarudzo yekukurumidza kwazvo. HTTP, nekuda kwezvikonzero zvakasarudzwa pamusoro, hazvimiriri mubereko mune iyi mamiriro, uye SMTP inotarisisa pakugadzirisa mabasa asiri iwo anosundira mushandisi akajairika. Naizvozvo, kana zvasvika pakumisikidza nekuona basa rakaringana remutengi mutengi, iwe unofanirwa kusarudza pakati pop3 uye imap.
Internet meseji yekuwana protocol (IMAP)
Muchiitiko chaunoda kuve nekushanda kwekuwana kune vese, kunyangwe iyo inonyanya kukosha e-mail, isu tinokurudzira kumisa sarudzo yako paImap. Kuzvakanakira protocol iyi, iwe unogona kutsanangura iyo yakasimbiswa synchronization, ichikubvumira kuti ushande netsamba pamidziyo dzakasiyana-siyana, uye nekutenda iyo mavara anodiwa anogara ari pedyo. Iko kukanganisa kukuru kweInternet meseji yekuwana protocol inotevera kubva pazvinhu zvekuvhiya kwayo uye kukurumidza kuzadza kwediski nzvimbo.
IMAP nezvimwe, hapana zvisingakwanisi zvakanakira - zvinokutendera kuti urongedze mavara muhurongwa hwekutumira mune hierarchical kurongeka, gadzira zvinyorwa zvakaparadzana uye isa mameseji ipapo, kureva kuti, kuita kwavo kuronga. Nekuda kweizvi, zvinokwanisika kuronga nyore nyore nyore uye zvakanaka basa rekunyorerana kwemagetsi. Nekudaro, imwezve kusagadzikana kunotevera kubva kune inobatsira basa rinobatsira - pamwe nekudhinda kwenzvimbo yemahara pane diski, pane mutoro wakawedzerwa pane processor negondohwe. Neraki, izvi zvinoonekwa chete mukuenzanisa maitiro, uye chete pane zvakaderera-simba zvishandiso.
Post office protocol 3 (pop3)
Pop3 inokodzera kumisikidza iyo tsamba yekutumira tsamba kana kuvapo kwenzvimbo yemahara pane server (drive) uye kumhanya kwakanyanya kwebasa kunokosha. Izvo zvakakosha kuti unzwisise zvinotevera: Kumisa sarudzo yako pane iyi protocol, unoramba kuyananisa pakati pemidziyo. Ndokunge, kana iwe ukagamuchira, semuenzaniso, mavara matatu pane iyo nhamba yekisimusi 1 uye akazviona seyakaverenga, pane iyo nhamba yechipiri, zvakare ichishanda pane post office protocol 3, havazomirwi vakadaro.
Izvo zvakanakira pop3 zvinosanganisira chete kuponesa disk nzvimbo, asiwo mukushayikwa kweanenge mashoma anooneka mutoro paCPU neRam. Iyi protocol, zvisinei neiyo mhando yeInternet yekubatanidza, inokutendera kuti uise mavara eyemagetsi zvizere, kureva, nezvinhu zvese zvemukati uye mari. Ehe izvi chete zvinoitika kana zvakabatana, asi heino zvinoshanda zvakanyanya imp, pasi pekurima traffic kana kumhanya kwakadzika, iwo misoro yavo icharatidza zvachose, uye yakawanda yezvinyorwa ichasiya kusevha "Kusvika panguva dziri nani".
Mhedziso
Munyaya ino takaedza kupa mhinduro yakatsanangurwa uye inonzwisisika kumubvunzo, chii chinonzi email protocol. Pasinei nenyaya yekuti vese vari vana, chete - imap uye pop3 vanofarira mushandisi akajairwa. Yekutanga inoda kufarira avo vanoshandiswa kushandisa tsamba kubva pane zvakasiyana midziyo, kuti vakurumidze kuwana zvachose kune ese (kana madikanwa) mavara, rurongerwo. Yechipiri yakanyanya kutongwa - inokurumidza kuita basa, asi isingatenderi kuronga kamwechete pamidziyo yakati wandei.
