[SunHELP] System Wide SPAM solution

[Shain Miley]

Hi,
Can anyone recommend some kind of system wide spam filter that runs on
Solaris?  I am using Sendmail and thinking about configuring procmail as
well.  The problem is that it looks like in order use some of this stuff
you need to add files (.procmailrc) for example in each users home dir. 
With over 400 mail users I am hoping to avoid this.   I would much
prefer to have 3 or 4 main .conf files or something like that...any
ideas?  Thanks.
