Read All Email from POP3 Inbox by Message Numbers

Demonstrates how to read all of the email from a POP3 inbox by fetching each email by it's message number. Ruby

require 'chilkat'

success = false

# This example requires the Chilkat API to have been previously unlocked.
# See Global Unlock Sample for sample code.

mailman = Chilkat::CkMailMan.new()

# Set the POP3 server's hostname
mailman.put_MailHost("pop.example.com")

# Set the POP3 login/password.
mailman.put_PopUsername("myLogin")
mailman.put_PopPassword("myPassword")

# Get the number of messages in the mailbox.
numMessages = mailman.GetMailboxCount()

# Message numbers are specific to a POP3 session. 
# If a maildrop (i.e. inbox)  contains 10 messages, 
# the message numbers will be 1, 2, 3, ... 10. 
# If message number 1 is deleted and a new POP3 session 
# is established, there will be 9 messages numbered 1, 2, 3, ... 9. 

i = 1

email = Chilkat::CkEmail.new()
while i <= numMessages
    # Fetch by the message number (not by the UIDL)
    success = mailman.FetchOne(false,0,i,email)
    if (success == false)
        print mailman.lastErrorText() + "\n";
        exit
    end

    print email.ck_from() + ": " + email.subject() + "\n" + "\n";

    i = i + 1
end
