Modify Email on IMAP Server?

Question:

I was wondering how it would be possible to make changes to an email on the server.

Answer:

Once an email is on a server, it cannot be modified.  This is not a Chilkat limitation, but it’s the way mail servers work.  However, with IMAP you may download an email, make changes, upload the new email to the mailbox via one of the Chilkat.Imap.Append* methods, and then delete the old email.  The new email will have a new UID assigned by the IMAP server, so it’s technically not the same email..
