How to Download Messages in MessageSet One at a Time

See more IMAP Examples

If a message set contains a huge number of emails, it's NOT a good idea to try to download all at once into an email bundle using a method such as FetchBundle. It's better to iterate over the messages in the set to download one by one. Chilkat2-Python

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

imap.Port = 993
success = imap.Connect("imap.example.com")

# Authenticate
success = imap.Login("email_account_login","email_account_password")

# Search for messages and return a set of matching messages.
