However, if the client does so, Dovecot will set the mtime of the Maildir file in question to the date specified by the client even if it's in the future. Since files with an mtime in the future can cause all sorts of trouble (e.g., they might get backed up repeatedly by incremental backups), it would be nice if Dovecot would (optionally?) use the current time if the client specifies a time in the future.
Hmm. I don't really like violating a SHOULD. And I don't like adding a setting to do it either. There are already too many settings.
I wonder how big of a problem this actually is. Are people often backing up based on mtime?
For example, we use the following patch:
This is a problem only with Maildir, so if the code is added it should go to maildir-save.c.
