Mark IMAP Email as Read/Unread (Seen/Unseen)

Demonstrates how to mark emails as read or unread. CkPython

import sys
import chilkat

success = False

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

imap = chilkat.CkImap()

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

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

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

# Set PeekMode so that downloaded messages are not
# automatically marked as seen.
imap.put_PeekMode(True)

# The NumMessages property contains the number of messages 
# in the currently selected mailbox.
numMsgs = imap.get_NumMessages()
if (numMsgs == 0):
    sys.exit()

email = chilkat.CkEmail()

for i in range(1,(numMsgs)-1):
    # Download each email by sequence number (not UID)
    success = imap.FetchEmail(False,i,False,email)
    if (success == False):
        print(imap.lastErrorText())
        sys.exit()

    # If desired, mark the email as SEEN.  There are two
    # ways to do it:

    # 1) Set the flag directly by using the sequence number
    # Indicate that we are passing a sequence number and
    # not a UID:
    bIsUid = False
    # Set the SEEN flag = 1 to mark the email as SEEN,
    # or set it to 0 to mark it as not-seen.
    success = imap.SetFlag(i,bIsUid,"SEEN",1)
    if (success == False):
        print(imap.lastErrorText())
        sys.exit()

    # 2) Alternatively, we can use the email object.
    # When an email is downloaded from the IMAP server
    # Chilkat will add a "ckx-imap-uid" header to the email.
    # This makes it possible to know the UID associated with
    # the email.  (This is not the sequence number, which may change
    # from session to session, but the UID which does not change.
    # The SetMailFlag method is identical to SetFlag, except
    # it gets the UID from the ckx-imap-uid header.
    # For example:
    success = imap.SetMailFlag(email,"SEEN",1)
    if (success == False):
        print(imap.lastErrorText())
        sys.exit()

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