Plugin Installation

[HOMA S. <hom...@gm...>]

Hi all
I 'm brand new to qmail-spp.I installed netqmail1.06 and
ucspi-tcp-0.88  as described in Life with Qmail with vpopmail
5.4.27(without Database).I Also applied the qmail-smtpd-auth-043 for
authentication.
I want to use qmail-spp plugins such as
vpopmail_check_recipient,maxrcpt,rate_from and so on but unfortunately
do not know how should i use these plugins.I appreciate any help about
installing these patches.
Best Regards
H.Saadat
