Just for our dear fellows information,
I removed my trial 5.5 sme server's qmail system with those **smtpd and installed a whole qmail package - qmail toaster
Althrough some adjustment needed to fix up the file mapping, it work. I am going to try to install a better control SPAM system later this week with virus filter. ;D I let you know how it work.
So far I am very happy with the new qmail and thank you very much for Miguel's work.
Cheers ; )
