Addusers script

[Sumith Ail]

Hello   I am using a adduser.pl script to add a lot of users to my Qmail+Vpopmail system but I am trying to add around 2000 users and not all of them are getting added in vpopmail. I can see the users in qmailadmin but neither their directories are created nor they can POP3 login   Can someone please send me a working addusers script which can add around 2000 users in one go.   Thanks Sumith
