Help with procmail mailing list

I need to find out for sure whether or not Solaris 10x86 comes with procmail installed? I only need it for mail subscription "Only"
WE have about 51 mailing lists subscriptions from listproc.
I need help just doing mailing lists.
How to best go about this?
I downloaded version for Solaris 10x86
We are running a listproc "old" version on Solaris 9 sparc, according to my app person she tells me that I can just transfer it over is this true?
I thought it was OS dependent.
We need the ability to do the auto-sub doesn't require anything fancy... just needs to allow
1) email-based subscriptions from a manager account
2) ability to track current and former subscribers of a list.
The latter was the one that was completely do-able in listproc but required a bit of a turn around the barn. I suspect it'll be easy in any newer application.
Any help would be appreciated
