Will changing the quota to 80Meg for a user with "dbmail-adduser c" i notice that listing the user with "dbmail-adduser s" give me 76Meg.
Looking into " user.c" i notice that after the instruction case "M" you set newsize to 1000000 it should be (1024 x 1024) that is 1048576. and after instruction case "K" you set newsize to 1000 it should be 1024. Hope you correct "user.c" for all Jacques Beaudoin Montreal
