Nonsense. You can set atime and mtime to anything you want. SOP for writing to to an mbox formatted mailbox is to preserve the atime (changing only the mtime) so that other programs know that that there is "new" mail in the mbox. I know mutt works that way, and I believe that the "you've got new mail" features in some shells work that way. AFAIK, atime<mtime has been the "standard" way to determine when an mbox contains new mail for at least 20 years. Anybody writing to an mbox mailbox has to follow the rules if they expect to interoperate with other mail applications. If mailbox.mbox.add() doesn't preserve the atime when writing to an mbox, then mailbox.mbox.add is broken. http://www.qmail.org/qmail-manual-html/man5/mbox.html -- Grant Edwards grante Yow!
