Ok, I am a complete newbie on linux but I'm trying to learn! I am using a vps with a provided cent os 5 HIAB "hardend" image. This also has lxadmin preloaded which I am using to configure my mail accounts.

I'm trying to install mailman and this line appears in there config documentation.

"BN: it highly depends on your mail storing policy. For example if you use the simple ~alias/.qmail-* files, you can use `id -g alias`. But if you use /var/qmail/users, the specified mail gid can be used. "

How can I tell if I'm using one or the other? I do have .qmail files in my home directories but I also have in in my /var/qmail/users/cdb file.

Thanks for any help
