5.14.1 What can I use the POP3MailService for?
Using this service, applications can retrieve one or more messages from the email store for a nominated user, access the details and contents of the individual messages, including the sender details, subject, body text and file attachments, and request that processed messages be deleted from the mail server.
The POP3MailService supports decrypting secure messages that have been encrypted with the recipient's public key.
