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 Perl
