IMAP e POP3

Leggi tutto quello che c’è da sapere su IMAP e POP3

IMAP e POP3 sono due diversi protocolli per la trasmissione di email. Questi protocolli vengono utilizzati per scaricare i messaggi di posta elettronica dai server di posta. Per semplificare, se stai utilizzando un client di posta elettronica, puoi configurarlo con IMAP o POP3 per salvare tutte le tue email su un computer o qualsiasi altro dispositivo che possiedi.

Sta a te decidere se vuoi usare POP3 o IMAP. Di seguito abbiamo spiegato cosa fa ognuno di questi protocolli email e quali sono le differenze tra IMAP e POP3.

Significato di POP3

POP3 sta per Post Office Protocol version 3. Una delle differenze tra IMAP e POP3 è che POP3 è più semplice di IMAP. L’unico compito di POP3 infatti, è scaricare le email sui tuoi dispositivi da un server di posta. In particolare POP3 scarica solo le email che si trovano nella cartella Posta in arrivo. Non scarica cioè, le email contenute nella cartella dello spam, delle bozze, dei messaggi inviati o delle email eliminate.

POP3 non si sincronizza. Ciò significa che una volta scaricate le email da un server di posta, quest’ultimo eliminerà le email. Pertanto, non ci sarà alcuna copia salvata sul server di posta una volta che POP3 l’avrà scaricata.

Se disponi di due computer quindi, e uno dei due scarica le tue email dal server di posta, l’altro non sarà in grado di recuperarle, poiché saranno già state eliminate.

Vantaggi di POP3

  • POP3 utilizza la larghezza di banda in modo più efficiente rispetto a IMAP. Ciò è particolarmente utile se si dispone di connessioni Internet lente.
  • Non ci sono limiti alle dimensioni della tua casella di posta con POP3.

Significato di IMAP

IMAP sta per Internet Message Access Protocol. IMAP ti consente di visualizzare le email presenti sul server di posta da più dispositivi. Non solo le email vengono salvate sul server di posta, ma IMAP ne memorizza anche delle copie su tutti i tuoi dispositivi.

Inoltre, IMAP sincronizza tutte le tue cartelle. A differenza di POP3, oltre alla cartella della posta in arrivo, sincronizza anche le cartella della posta inviata, eliminata e così via.

Quando utilizzi IMAP, se elimini una email salvata sul tuo smartphone, essa verrà automaticamente eliminata dal tuo computer e dal server di posta. Lo stesso vale quando crei una cartella, la cartella verrà visualizzata automaticamente anche sul tuo computer e sul server di posta elettronica.

Vantaggi di IMAP

  • Se decidi di cambiare client di posta elettronica, con IMAP puoi trasferire facilmente tutti i tuoi vecchi archivi di posta elettronica verso il tuo nuovo programma. Bastano solo pochi minuti per scaricare facilmente tutte le tue email dal server.
  • Quando scegli un’email configurata con IMAP su one.com, tutte le tue email avranno una copia salvata sul server di posta. Ciò significa che se il tuo computer si rompe o viene rubato, non dovrai preoccuparti di perdere i tuoi dati. Il nostro sistema di backup su one.com protegge la tua posta da tutti i rischi immaginabili.
  • A differenza di POP3, IMAP salva sempre una copia delle tue email. Pertanto, ti consente di recuperare più volte le email dal server di posta, visto che una copia di esse sarà sempre presente sul server fino a quando non decidi di eliminarla.

POP3 o IMAP?

Quindi, quale protocollo di posta elettronica dovresti scegliere?

Dovresti scegliere POP3, se hai intenzione di scaricare la tua posta solo una volta su un unico dispositivo.

Anche se non disponi di una connessione Internet, potrai comunque visualizzare le tue email utilizzando POP3. Inoltre, risparmierai molto spazio di archiviazione sul tuo server di posta elettronica, poiché le email vengono eliminate ogni volta che vengono scaricate sul tuo dispositivo.

Dovresti usare IMAP, se utilizzi più dispositivi.

IMAP salva una copia di tutte le tue email sul server di posta, il che significa che non dovrai preoccuparti di perdere i dati. Inoltre, sarai in grado di vedere tutte le tue cartelle, che avranno lo stesso aspetto su tutti i tuoi dispositivi.
