Demonstrates how to copy the entire contents of an IMAP mailbox to another IMAP server.

Note: This example requires Chilkat v11.0.0 or greater.

Chilkat Python Downloads install with pip pip3 install chilkat or download... Python Module for Windows, MacOS, Linux, Alpine Linux

import sys

success = False

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

imapSrc = chilkat.CkImap()

# Connect to our source IMAP server.
success = imapSrc.Connect("imap.example.com")
if (success == False):
    print(imapSrc.lastErrorText())
    sys.exit()

# Login to the source IMAP server
success = imapSrc.Login("admin@chilkatsoft.com","myPassword")
if (success == False):
    print(imapSrc.lastErrorText())
    sys.exit()

imapDest = chilkat.CkImap()

# Connect to our destination IMAP server.
success = imapDest.Connect("mail.example-code.com")
if (success == False):
    print(imapDest.lastErrorText())
    sys.exit()

# Login to the destination IMAP server
success = imapDest.Login("myLogin","myPassword")
if (success == False):
    print(imapDest.lastErrorText())
    sys.exit()

# Select an IMAP mailbox on the source IMAP server
success = imapSrc.SelectMailbox("Inbox")
if (success == False):
    print(imapSrc.lastErrorText())
    sys.exit()

# After selecting a mailbox, the NumMessages property will
# be updated to reflect the total number of emails in the mailbox:
print(str(imapSrc.get_NumMessages()))

# The emails in the mailbox will always have sequence numbers
# ranging from 1 to NumMessages.

# This example will copy the first 10 messages using sequence numbers
sbMime = chilkat.CkStringBuilder()

for seqNum in range(1,11):
    sbMime.Clear()
    success = imapSrc.FetchSingleAsMimeSb(seqNum,False,sbMime)
    if (success == False):
        print(imapSrc.lastErrorText())
        sys.exit()

    success = imapDest.AppendMimeWithFlagsSb("Inbox",sbMime,False,False,False,False)
    if (success == False):
        print(imapDest.lastErrorText())
        sys.exit()

# Disconnect from the IMAP servers.
success = imapSrc.Disconnect()
success = imapDest.Disconnect()
