Sorting should then be done by top-level-domain first. Then 2nd, 3rd... and last by user. [EMAIL PROTECTED] < [EMAIL PROTECTED] and [EMAIL PROTECTED] < [EMAIL PROTECTED] we get then the order: [EMAIL PROTECTED] < [EMAIL PROTECTED] < [EMAIL PROTECTED] < [EMAIL PROTECTED] rather than (in normal text-order): [EMAIL PROTECTED] < [EMAIL PROTECTED] < [EMAIL PROTECTED] < [EMAIL PROTECTED] Tommi ---------------------------(end of broadcast)--------------------------- TIP 4: Don't 'kill -9' the postmaster
