First of all, THANKS to all of you for your valuable input...

I think I found a solution that works cleanly an Solaris 10. Olivers 
hint to look more closely at malloc put me on the right track:

Solaris 10 provides several libraries with implementation of malloc 
different from the standard malloc shipped with libc. So if you link 
milter-greylist to libumem (or libbsdmalloc) the memory consumption 
stays at a normal level. (see: man libumem [man libbsdmalloc])

Here is basically what I'm using to build milter-greylist:

#!/bin/sh 
 

CC=gcc
LIBS="-lumem"
LDFLAGS="-L/usr/local/lib"
LDFLAGS="$LDFLAGS -R/usr/local/lib"
CFLAGS="-I/usr/local/include"
export LIBS
export LDFLAGS
export CC
export CFLAGS
./configure --enable-dnsrbl --sysconfdir=/etc/mail --with-user=smmsp
gmake


I hope this of help also to someone else,
