[otrs] emails

Good day Please can someone help me I am tying to get email onto system, I tried activating the CustomerGroupSupport with this line $Self->{'CustomerGroupSupport'} = '0'; in Config.pm but it is not working, it works when I run cat ../doc/test-email-1.box|./PostMasterPOP3.pl and I do not think I have to always do that to get emails onto the system. I have Installed otrs2.0.4 on SUSE Linux Thanks Mamakwa
