(Properly working MDA doesn't update atime when storing a message in an mbox-type mailbox. MUA then sees mtime > atime, and marks the mailbox as having new mail.) -- FreeBSD 4.4-STABLE 7:16PM up 11 days, 1:39, 21 users, load averages: 0.04, 0.05, 0.05 To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-questions" in the body of the message
