samba - Mar 1998 - Samba 18p3, Sol. 251 and CCmail 6.01

Hi-
     I'm currently using Samba 18p3 on Solaris 2.5.1 and am considering 
     placing a CC:mail post office on it for W95/WNT cc:mail clients.
     
     Will it work? Any problems with file locking, etc.?
     
     All inputs are appreciated.
     Thanks,
     Dennis
