Preserve unseen email flag

Question

I have 10 customers, one for each mail box on Aruba IMAP server.

Every first access into the Inbox folder seems that all mail is marked as “seen”

If I close the application and restart it, I can't really detect whitch mail are "seen" and whitch are "unseen".

Reading some faq in your site, I understood that some server mark the email as seen, perhaps the problem could be from

imap.GetMessageInfoByUID(uids)

and the suggestion is to use imap.PeekMessageByUID(uids) instead of imap.GetMessageInfoByUID(uids).

It is a correct solution?

Answer 1

Yes, this is correct solution.

GetMessageInfoByUID marks message as seen on the IMAP server (adds \SEEN flag) while PeekMessageByUID doesn't.

Apart from that both methods work exactly the same.
