Lua Requires Chilkat v11.0.0+

Move Selected Emails to another Mailbox Folder

See more IMAP Examples

Downloads emails one by one in a selected mailbox, decides which emails are to be moved, and then moves the set of messages to another mailbox folder. Lua

    -- In the following call to loadlib, change the path (./chilkat.dll) to the relative or absolute directory where the chilkat.dll, chilkat.so, or chilkat.dylib is located.

    --  Normally, when an email is downloaded, its "Seen" flag is automatically set.

    --  After selecting the mailbox, the NumMessages property
    --  will contain the number of emails in the mailbox.
    --  When sequence numbers (not UIDs) are used to reference emails,
    --  they range from 1 to N, where N is the number of messages in the mailbox.
    --  This example will download the headers by sequence numbers.

    --  Fetch each email and decide for each if it is to be moved
    --  to a particular other mailbox.  If so, we'll add the sequence number to
    --  the mset, and then move all emails in the mset to the other mailbox.
