Please **close** this thread I found my mistake : in /home/vpopmail/include/vpopmail_config.h
/* #undef CLEAR_PASS */ I forgot to compile with --enable-clear-passwd=y option All lines after postmaster line are not read by qmailadmin in /home/vpopmail/domains/adomain.com/vpasswd because when adding a domain with vpopmail without enable clear passwd It looks like that postmaster:CRYPTPASS.:2:0:Postmaster:/home/vpopmail/domains/adomain.com/post master:NOQUOTA without enable clear passwd, it have a better look :) postmaster:CRYPTPASS.:2:0:Postmaster:/home/vpopmail/domains/adomain.com/post master:NOQUOTA:CLEARPASS and it works...
