One common problem when a mailbox is accessed through both fetchmail
(with keep option) and an email client is that when a mail which has
been viewed through the email client does not get downloaded.
One solution for imap is to use an alternate flag. [...]
Should this feature be added to fetchmail?
I don't think so. There are a couple reasons this strikes me as a bad idea.
1. It would be specific to IMAP.
2. It moves fetchmail towards being an email client. Fetchmail is not
designed to be an email client; it's designed to be a protocol gateway.
