Version: 1.6.2 (using KDE KDE 3.2.1) Installed from: SuSE RPMs KMail only supports two priorities: "normal" and "urgent". I occationally find it useful to mark an email as low priority (below normal). Netscape supported 5 (highest, high, normal, low, lowest), but 3 will do (urgent, normal, low) in all situations I can think of. "low" is a polite way of telling the recipient to read it whenever he has time. Bug 22119 "support for priorities" and 29775 "No mail priority flags" is related.
