Hi, RFC 2060 prefers, but does not require, that IMAP servers preserve flags during copy operations. My experience (using the Mail::IMAPClient module) is that it does not.
Does it? Thanks, Ian -- 6.4.7. COPY Command Arguments: message set mailbox name Responses: no specific responses for this command Result: OK - copy completed NO - copy error: can't copy those messages or to that name BAD - command unknown or arguments invalid The COPY command copies the specified message(s) to the end of the specified destination mailbox. The flags and internal date of the message(s) SHOULD be preserved in the copy.
