Question:
I have an email with a very long text in my inbox and would like to limit the download when fetching this email via CkoImap. Is this possible when using a mass-fetch operation of a bundle?
If you can use POP3 instead of IMAP, the MailMan component has methods (GetAllHeaders, GetHeaders) that allow you to truncate the number of body lines returned. I don't think the same is available in IMAP.
