POP3 anv\u00e4nds f\u00f6r att \u00f6verf\u00f6ra e-post. Det \u00e4r den tredje versionen av postprotokollet. Med ett POP3-aktiverat e-postprogram kan du h\u00e4mta e-postmeddelanden fr\u00e5n en server. Beroende p\u00e5 inst\u00e4llningen raderas e-postmeddelandena efter h\u00e4mtning p\u00e5 servern och lagras sedan endast p\u00e5 din slutenhet (dator, surfplatta, smartphone eller liknande). Du tar praktiskt taget ut posterna ur brevl\u00e5dan p\u00e5 servern f\u00f6r inkommande post, som tillf\u00e4lligt lagrar dem \u00e5t dig tills du h\u00e4mtar dem, precis som du tar ut ett klassiskt brev ur din brevl\u00e5da. E-post\u00f6verf\u00f6ringsprotokollet POP3, ett s\u00e5 kallat ASCII-protokoll, beskrivs i detalj i den internationellt giltiga regeln RFC 1939 och anv\u00e4nder i allm\u00e4nhet port 110 eller, i det krypterade fallet, 995, vilket kan beh\u00f6va aktiveras i brandv\u00e4ggsreglerna.<\/p>\n
Post Office Protocol utvecklades f\u00f6rst f\u00f6r Unix-omr\u00e5det, men kan nu anv\u00e4ndas fr\u00e5n n\u00e4stan alla operativsystem om l\u00e4mplig e-postprogramvara installeras p\u00e5 dem. POP3 har anv\u00e4nts sedan 1988 och har kontinuerligt anpassats, oftast i mindre omfattning, till den aktuella utvecklingen av dator- och Internettekniken. POP1 utvecklades redan 1984 och ersattes av POP2 bara ett \u00e5r senare. POP4, som \u00e4r t\u00e4nkt att st\u00f6dja ytterligare funktioner j\u00e4mf\u00f6rt med POP3, har \u00e4nnu inte lyckats etablera sig. Med POP3S \u00e4r det nu ist\u00e4llet m\u00f6jligt att \u00f6verf\u00f6ra anv\u00e4ndardata i krypterad form. F\u00f6r enkel och tydligt listad e-posth\u00e4mtning kan du fortfarande anv\u00e4nda POP3 eller POP3S, vilket \u00e4r f\u00f6rinst\u00e4llt i de flesta aktuella e-postklienter, via en s\u00e4ker SSL-anslutning (eller TSL-anslutning).<\/p>\n
F\u00f6r att kunna h\u00e4mta e-postmeddelanden som mottagits p\u00e5 servern kr\u00e4vs autentisering efter det att anslutningen till servern har uppr\u00e4ttats. Anv\u00e4ndarnamnet lagras i e-postprogrammet. L\u00f6senordet kan ocks\u00e5 sparas, men av s\u00e4kerhetssk\u00e4l b\u00f6r man komma \u00f6verens om en f\u00f6rfr\u00e5gan i inst\u00e4llningarna. D\u00e4refter beg\u00e4rs l\u00f6senordet. Dessa inloggningsuppgifter \u00f6verf\u00f6rs nu till servern. Den sistn\u00e4mnda startar sedan den faktiska \u00f6verf\u00f6ringen av dina e-postmeddelanden, en efter en. N\u00e4r alla e-postmeddelanden som finns p\u00e5 servern har \u00f6verf\u00f6rts utf\u00f6r servern vanligtvis ett delete-kommando. Undantag: Du har st\u00e4llt in ditt klientprogram s\u00e5 att de meddelanden som redan har tagits emot l\u00e4mnas kvar p\u00e5 servern. Detta undantag fungerar dock endast om din e-postleverant\u00f6r till\u00e5ter och tillhandah\u00e5ller ett s\u00e4rskilt till\u00e4gg som egentligen inte h\u00f6r till POP3. Efter h\u00e4mtningen avbryts anslutningen mellan server och klient.<\/p>\n
En f\u00f6rdel \u00e4r att du inte beh\u00f6ver vara uppkopplad hela tiden, utan bara n\u00e4r posten h\u00e4mtas. Det finns dock ingen synkronisering mellan flera klientenheter, vilket \u00e4r en nackdel. Detta inneb\u00e4r att du inte automatiskt har samma status p\u00e5 din e-post fr\u00e5n alla terminaler. POP3 hanterar praktiskt taget bara processen att lista, h\u00e4mta och radera e-postmeddelanden. Om du vill ha mer funktionalitet \u00e4r det l\u00e4mpligt att anv\u00e4nda ett annat e-postprotokoll, t.ex. IMAP<\/a> som ska v\u00e4ljas ut. I fallet med enkel POP3 \u00f6verf\u00f6rs en del av anv\u00e4ndardata i klartext. POP3S \u00e4r n\u00e5got s\u00e4krare.<\/p>\n F\u00f6ruts\u00e4ttningar f\u00f6r att h\u00e4mta e-post via POP3 \u00e4r korrekta inst\u00e4llningar i klientens e-postprogram. Beroende p\u00e5 operativsystemet och e-postprogrammet kan de vara mer eller mindre omfattande. De grundl\u00e4ggande funktionerna \u00e4r dock desamma i alla e-postklienter. V\u00e4lj f\u00f6rst POP3 som \u00f6verf\u00f6ringsmetod. F\u00f6rst beh\u00f6ver du den e-postadress som du tidigare har registrerat hos e-postleverant\u00f6ren, din Anv\u00e4ndarnamn<\/a> och motsvarande l\u00f6senord. Dessutom kan namnet eller IP-adress<\/a> f\u00f6r servern f\u00f6r inkommande e-post kr\u00e4vs. De flesta moderna e-postprogram s\u00f6ker sj\u00e4lva efter den ansvariga servern efter att ha angett e-postadressen. Annars kan du hitta det n\u00f6dv\u00e4ndiga servernamnet p\u00e5 e-postleverant\u00f6rens supportsidor. Med vissa e-postprogram \u00e4r det ocks\u00e5 m\u00f6jligt att skapa en ny e-postadress via detta program. Som en motsvarighet till POP3 beh\u00f6ver du fortfarande en server f\u00f6r utg\u00e5ende e-post, som i allm\u00e4nhet kan skicka dina e-postmeddelanden via SMTP (Simple Mail Transfer Protocol) eller, p\u00e5 senare tid, ofta via ESMTP (Extended Simple Mail Transfer Protocol). Ofta anv\u00e4nder leverant\u00f6rerna samma server som f\u00f6r utg\u00e5ende e-post. I vilket fall som helst hittar du namnet p\u00e5 den ansvariga servern p\u00e5 samma st\u00e4lle som namnet p\u00e5 POP3-servern. De flesta e-postklienter st\u00e4ller automatiskt in de n\u00f6dv\u00e4ndiga in- och utg\u00e5ngsportarna. Vid behov finns de ocks\u00e5 f\u00f6rtecknade p\u00e5 leverant\u00f6rens st\u00f6dsidor.<\/p>","protected":false},"excerpt":{"rendered":" POP3 wird zur \u00dcbertragung von eMails eingesetzt.
