Skr\u00f3t IMAP oznacza Internet Message Access Protocol. Jest to protok\u00f3\u0142 dost\u0119pu do poczty elektronicznej w komercyjnie dost\u0119pnych standardowych programach pocztowych. W protokole IMAP wiadomo\u015bci e-mail s\u0105 wysy\u0142ane i odbierane poprzez po\u0142\u0105czenie z serwerem. Ponadto mo\u017cna obejrze\u0107 tylko temat, a ca\u0142\u0105 tre\u015b\u0107 e-maila mo\u017cna obejrze\u0107 tylko poprzez dodatkowe pobranie. Poszczeg\u00f3lne foldery mog\u0105 by\u0107 przypisane, e-maile mog\u0105 by\u0107 przenoszone, usuwane lub wyszukiwane. Ponadto na serwerze mo\u017cna tworzy\u0107 od podstaw r\u00f3\u017cne foldery. Mo\u017cliwe jest r\u00f3wnie\u017c, na przyk\u0142ad, wyszukiwanie wy\u0142\u0105cznie okre\u015blonych za\u0142\u0105cznik\u00f3w do wiadomo\u015bci e-mail. E-mail<\/a> do przeszukania.<\/p>\n

POP3 i jego funkcje w por\u00f3wnaniu z IMAP<\/h2>\n

Wiadomo\u015bci e-mail odczytywane za po\u015brednictwem protoko\u0142u Post Office Protocol 3 nie s\u0105 ju\u017c dost\u0119pne na serwerze. Natomiast wiadomo\u015bci e-mail w formacie IMAP mog\u0105 by\u0107 odczytywane przez kilka urz\u0105dze\u0144 i zawsze pozostaj\u0105 w pami\u0119ci. Usuni\u0119cie na serwerze nast\u0119puje tylko wtedy, gdy wiadomo\u015bci e-mail s\u0105 usuwane r\u0119cznie. Bie\u017c\u0105cy stan jest r\u00f3wnie\u017c zawsze synchronizowany.<\/p>\n

\"Mailing\"<\/a><\/p>\n

POP3<\/a> jedynie przesy\u0142a dalej e-maile, a nast\u0119pnie kasuje je ponownie na swoim serwerze. W celu trwa\u0142ej archiwizacji tych wiadomo\u015bci e-mail nale\u017cy utworzy\u0107 oddzielny magazyn. Z drugiej strony, korzystanie z przetwarzania poczty elektronicznej za pomoc\u0105 IMAP jest ca\u0142kowicie proste. W tym przypadku wiadomo\u015bci e-mail pozostaj\u0105 na serwerze, a u\u017cytkownik nie musi podejmowa\u0107 \u017cadnych dalszych dzia\u0142a\u0144.<\/p>\n

W\u0142a\u015bciwo\u015bci IMAP<\/h3>\n

Protok\u00f3\u0142 tekstowy IMAP umo\u017cliwia serwerowi dost\u0119p do okre\u015blonych wiadomo\u015bci e-mail w folderze. Mo\u017cliwe jest r\u00f3wnie\u017c otwarcie konkretnej wiadomo\u015bci e-mail. Poniewa\u017c wszystkie e-maile s\u0105 przechowywane na Serwer<\/a> pozosta\u0107 uratowany, nie ma potrzeby ratowa\u0107 lokalnie. Aby uzyska\u0107 dost\u0119p do tych folder\u00f3w, konieczne jest aktywne po\u0142\u0105czenie z Internetem. Wszystkie przychodz\u0105ce wiadomo\u015bci e-mail s\u0105 zapisywane i odpowiednio synchronizowane po przywr\u00f3ceniu po\u0142\u0105czenia internetowego, tak aby by\u0142y widoczne dla u\u017cytkownika. Dzi\u0119ki IMAP IDLE mo\u017cliwe jest wysy\u0142anie wiadomo\u015bci typu \"push mails\", kt\u00f3re s\u0105 zg\u0142aszane natychmiast po ich otrzymaniu. Technologia pushmail zapobiega dalszemu przep\u0142ywowi danych i znacznie oczyszcza ca\u0142y system. Na pierwszy rzut oka wida\u0107 od razu, jakie nowe e-maile pojawi\u0142y si\u0119. Jednak w celu zachowania zgodno\u015bci z przepisami o ochronie danych osobowych, po\u0142\u0105czenia z serwerem s\u0105 szyfrowane. Wszak\u017ce wymiana poczty elektronicznej oznacza, \u017ce wiele osobistych Dane<\/a> kt\u00f3re maj\u0105 wp\u0142yw na interesy ochrony danych osoby fizycznej.<\/p>\n

Zalety IMAP<\/h3>\n

IMAP charakteryzuje si\u0119 wieloma zaletami. Zw\u0142aszcza w przypadku dost\u0119pu do wiadomo\u015bci e-mail z kilku urz\u0105dze\u0144 mobilnych, sta\u0142a synchronizacja ma t\u0119 zalet\u0119, \u017ce status wiadomo\u015bci e-mail jest zawsze aktualny. Dodatkowo, dost\u0119p do konta e-mail mo\u017cna uzyska\u0107 z kilku urz\u0105dze\u0144 jednocze\u015bnie. Nie tylko mo\u017cna wywo\u0142a\u0107 lub odczyta\u0107 e-mail. Wiadomo\u015bci e-mail mog\u0105 by\u0107 r\u00f3wnie\u017c przetwarzane jednocze\u015bnie. System operacyjny danego urz\u0105dzenia nie jest istotny. Mo\u017cliwe jest jednoczesne korzystanie z wszystkich system\u00f3w operacyjnych. Oznacza to, \u017ce skrzynki pocztowe mog\u0105 by\u0107 przetwarzane przez kilku u\u017cytkownik\u00f3w. IMAP jest szczeg\u00f3lnie korzystny dla urz\u0105dze\u0144 ko\u0144cowych, kt\u00f3re nie wymagaj\u0105 intensywnego magazynowania. Wyszukiwanie wiadomo\u015bci e-mail odbywa si\u0119 bezpo\u015brednio na serwerze, kt\u00f3ry posiada wystarczaj\u0105c\u0105 pojemno\u015b\u0107 pami\u0119ci masowej. Oznacza to, \u017ce nawet z urz\u0105dzenia mobilnego mo\u017cna wygodnie pracowa\u0107 w du\u017cych skrzynkach pocztowych. Co wi\u0119cej, wszystkie ilo\u015bci danych s\u0105 ca\u0142kowicie zredukowane. Pozwala to na smuk\u0142e i przede wszystkim szybkie przetwarzanie wiadomo\u015bci e-mail. W przeciwnym razie nie by\u0142oby mo\u017cliwe przetworzenie e-maili w sensowny spos\u00f3b w kr\u00f3tkim rytmie przetwarzania. Procedura \"push\" przyspiesza dostarczanie wiadomo\u015bci e-mail, poniewa\u017c s\u0105 one dostarczane natychmiast.<\/p>","protected":false},"excerpt":{"rendered":"
