Determine the Number of Unseen Email Messages

Demonstrates how to determine how many unseen messages exist in an email account on an IMAP server. CkPython

import sys
import chilkat

success = False

# This example requires 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("***","***")
if (success == False):
    print(imap.lastErrorText())
    sys.exit()

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

# After selecting the mailbox. the total number of emails
# is immediately available:
totalNum = imap.get_NumMessages()
print("Num messages = " + str(totalNum))

# To determine the number of unseen messages, a call
# to Search is required, which returns the set of UIDs
# of all unseen messages.

# We can choose to fetch UIDs or sequence numbers.
fetchUids = True
messageSet = chilkat.CkMessageSet()
success = imap.QueryMbx("UNSEEN",fetchUids,messageSet)
if (success == False):
    print(imap.lastErrorText())
    sys.exit()

numUnseen = messageSet.get_Count()
print(str(numUnseen))

print("UIDs ----")

# Display the UIDs
i = 0
while i < messageSet.get_Count() :
    print(str(messageSet.GetId(i)))
    i = i + 1

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