Receive email with IMAP protocol

Automatically translated from English

In 4D v18, we introduced a new way to send emails. Then in 4D v18 R2, we added a new way to retrieve emails using POP3. Now in 4D v18 R4, we’re taking the first steps for a new way to handle the IMAP protocol. As we did for SMTP and POP3, there’s a new IMAP New transporter command to handle the IMAP protocol.

The Internet Message Access Protocol (IMAP) is an Internet standard protocol used by email clients to retrieve email messages from a mail server. This protocol makes it possible to manage multiple mailboxes, download emails, perform searches on the server, manage message state, and a lot more!

And with this first IMAP feature, you can add methods to the transporter to: have the list of the available mailboxes, select a mailbox, and receive email from the selected mailbox. Let’s see how.
