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

# Connect to an IMAP server.
# Use TLS
imap.put_Ssl(True)
imap.put_Port(993)
success = imap.Connect("imap.someMailServer.com")
if (success != True):
    print(imap.lastErrorText())
    sys.exit()

# Login
success = imap.Login("myLogin","myPassword")
if (success != True):
    print(imap.lastErrorText())
    sys.exit()

# Select an IMAP mailbox
success = imap.SelectMailbox("Inbox")
if (success != True):
    print(imap.lastErrorText())
    sys.exit()

# Once the mailbox is selected, the NumMessages property
# will contain the number of messages in the mailbox.
# You may loop from 1 to NumMessages to
# fetch each message by sequence number.

bUid = False

n = imap.get_NumMessages()
for i in range(1,(n)-1):

    # Download the email by sequence number.
    mimeStr = imap.fetchSingleAsMime(i,bUid)

    # ... your application may process each MIME string...

# An alternative is to download each email in the form of an
# email object, like this:

for i in range(1,(n)-1):

    # Download the email by sequence number.
    # email is a CkEmail
    email = imap.FetchSingle(i,bUid)

    # ... your application may process the email object...

# Disconnect from the IMAP server.
success = imap.Disconnect()
