Pop3 and IMAP

Bersoft Private Mail (BPM) supports both POP3 and IMAP mailboxes.

 

IMAP is the acronym for Internet Message Access Protocol. It enables an email client to access messages stored on a mail server. It is more modern and offers most features than POP3 (Post Office Protocol), which is the other major protocol for accessing mail messages.

From a practical viewpoint, the main difference is that when using POP3, messages are deleted from the email server automatically after they are downloaded, but when using IMAP, messages are not deleted from the email server until the users moves them to another  folder or deletes them explicitly.

Also, IMAP allows creating and deleting online folders and to supports moving messages (by drag and drop) between local and online folders and vice-versa, as well as between online folders in different IMAP accounts.

IMAP accounts will be added at the bottom of the list, as root folders, but POP3 accounts will be added as Local Folders, between the Queue and Sent folders, the first time the user gets email from them.

Notice that the left image shows an IMAP folder named "myMail@gmail.com". By clicking its Inbox subfolder the messages in that accounts will be downloaded and shown..

 

 

Different from other email programs, BPM deletes messages from IMAP folders to the local Trash folder, and saves IMAP sent messages to the local Sent folder..
