I mpazamo zenziwe. Iiphoso zenziwa ngokucacileyo ngokuqhelekileyo nge-imeyile: endaweni ye-imeyili oyilindeleyo, ufumana umyalezo wephutha-umyalezo wephutha le- POP , ukuba i-akhawunti yakho iqulunqwe ukulanda iimeyile usebenzisa oko, i-Post Office, iprotocol.
Iikhowudi zeemeko zePOP
Ezinye izinto zingahambi kakuhle kule nkqubo yokukhuphela iimeyile. Umncedisi oqhele ukufumana i-imeyile yakho ukusenokungayiphenduli yonke ifowuni. Okanye mhlawumbi iphasiwedi yakho ayiphutha (kodwa mhlawumbi iphasiwedi yomncedisi ayilunganga, ngenxa ye-software ye-glitch). Umncedisi unokuphinde asebenze kwiingxaki zangaphakathi kwaye uphendule ngekhowudi yephutha.
Ngethamsanqa, iseva yePOP icacile ngokucacileyo malunga nesimo sayo. Ngokuqinisekileyo uyazi izimpendulo ezimbini: i-positive + OK kunye ne-negative. Ewe, oku kukhankanyiweyo ukuba ufuna ukwazi into ehambileyo.
Njengoko kuvela, + Kulungile kwaye -ERR malunga nayo yonke ikhowudi entsha kufuneka ufunde ukuba ufuna ukuqonda imiyalezo yeepopositi ye-POP. Yonke enye ikhowudi yomgangatho: ulwimi loluntu. Kubonakala ukuba, iProtokholi ye-Post Office yenziwe ngabantu ngabantu. Ulwazi olubanzi malunga ne -ERER impendulo yesiphakeli inikezwa ngesiNgesi esilula , emva komyalezo -ERR . Nangona iiseva ze-POP zifunwa ukuba zinike le ngcaciso eyongezelelweyo, ininzi yenza.
Imiyalezo yeZiphutha zePOP
Into yokuqala engakwazi ukuhamba kakuhle (ngaphandle komncedisi wehla phantsi) yi-server ye-POP engaqapheli igama lakho lomsebenzisi. Mhlawumbi uthayibhile into engalunganga, mhlawumbi isiseko esisebenzisiweyo ukuba isebenzise abasebenzisi phantsi. Mhlawumbi umkhukula ukhusele yonke indawo yokugcina apho ibhokisi leposi ligcinwa kwi-ISP yakho.
Xa umncedisi wePOP engaqapheli igama lakho lomsebenzisi, liza kuphendula ngoku: -ERER ibhokisi leposi elingaziwa .
Emva nje kokuba igama lomsebenzisi liza iphasiwedi, kwaye elinye ithuba lokuphulwa. Iimpazamo, kunjalo, kuba ngaphandle kwephasiwedi engalingani negama lomsebenzisi ( -ERR iphasiwedi engavumelekanga ) iseva ye-POP ingena kwenye ingxaki. Ibhokisi leposi le-POP linokufikelela kuphela ngxilongo olungenayo ngexesha. Ukuba i-mail checker yakho sele ingene ngemvume kwi-akhawunti yakho ye-imeyile, inkqubo yakho ye-imeyili ayikwazi ukufikelela kwi-akhawunti efanayo ngexesha elifanayo. Kwiimeko ezinje, xa ibhokisi leposi sele livalelwe enye inkqubo, i-POP iseva kwakhona: -ERR akakwazi ukuvala ibhokisi lemeyile .
Emva kokungena ngempumelelo kwi-akhawunti, umxhasi we-POP uya kuqalisa ukufumana imiyalezo, enye ngexesha. Xa icela umyalezo kumncedisi, impendulo eyodwa engalunganga iyakwenzeka : -AYI myalezo onjalo . Kubonakala ngathi umthengi unengxaki. Impendulo efanayo iya kubuyiselwa xa umthengi we-imeyile ezama ukuphawula umyalezo wokususa okungekho (okanye sele uphawulwe ngokususa).
Xa iseshoni yePOP iphelile, yonke imilayezo ephawulwe ngokususwa idla ngokusisigxina ngumncedisi. Ukuba umncedisi we-POP akakwazi ukususa yonke imilayezo (mhlawumbi ngenxa yokunqongophala kwemithombo) ibuyisela impazamo: -ERR imilayezo ethile esusiweyo ayisuswanga .

Ekubeni iProtokholi ye-Post Office yinto elula, zizinto ezimbalwa kuphela ezinokungahambi kakuhle, kunye nemiyalezo embalwa yeeposenti. Zonke iiphoso ezibuyiselwe yi-POP iseva ngokwenene imilayezo kwaye ayikho nje iikhowudi ze-cryptic.
Ukuba iprogram yakho ye-imeyile iphendulela le miyalezo ephosakeleyo kwimilayezo kwiibhokisi eziphosakeleyo ezingachaziyo, kulunge ukuba uzame ngokwakho. Umlilo uphawule nge-DOS kunye ne-telnet ngqo kwi-akhawunti yakho ye-imeyile. Uhlobo lwe- telnet
Xa umncedisi ekwazisa ngokuzonwabisa, + landela inkqubo njengoko ichazwe kwi-Post Office Protocol kwaye kufuneka ukwazi ukufumanisa impazamo. Ubuncinane, ukuba yonke into isebenza kakuhle, uyazi ukuba ingxaki ikhona kumxhasi wakho we-imeyile, kungekhona i-imeyile yakho.
