POP3: Download the Mail Header Only

When retrieving email messages using POP3, it’s possible to retrieve just the message headers (which include information such as the sender, subject, and date) without downloading the entire message body.

Retrieving just the message headers can be helpful when you want to quickly scan the list of messages in your mailbox to decide which ones to download and read in full.

Starting with 4D v20, a new parameter is added to the .getMail() function of the POP3 transporter to receive your emails without the body. This function can be even more helpful if you use Gmail because it does not trigger the deletion of read emails.
