Hi,

my maillog file (/var/log/kloxo/maillog)

grows by entries like:

Oct 27 18:58:59 vps vpopmail[23781]: vchkpw-smtp: vpopmail user not found office@:222.52.118.213
Oct 27 18:59:07 vps vpopmail[23797]: vchkpw-smtp: vpopmail user not found office@:222.52.118.213
Oct 27 18:59:15 vps vpopmail[23809]: vchkpw-smtp: vpopmail user not found support@:222.52.118.213
Oct 27 18:59:23 vps vpopmail[23824]: vchkpw-smtp: vpopmail user not found support@:222.52.118.213

Please what this vchkpw-smtp: vpopmail means?
