Related to this Admin feature: http://www.directadmin.com/features.php?id=1324 new directadmin.conf option, default: reseller_can_reset_email_count=0 where 0 is the internal default (disabled). If you set it to 1, then all Resellers will have the ability to reset their User's send count to 0. You'd usually use this option with it: reseller_can_set_email_limit=1 as they could alternatively just increase the limit anway, so might as well let them reset the limit.
