Milter-greylist

Hello list!

I've compiled and installed milter-greylist-1.6rc1 on Solaris 9 (sparc).
It works fine to compile if you install the following:
- gcc
- flex
- bison
(and add the option CFLAGS=-D__EXTENSIONS__ to the Makefile)

(This, because of that Solaris lex and yacc is missing to many important feature)

Everything works fine, except for "peer" option (replication of greylist/whitelist data between MX-peers). I've tried to truss and "debug" as much as i can with the help from Emmanuel Dreyfus, but i'm stuck...

The message i get in the syslog looks like this:

Apparently "sync_sender" routine fails (problem binding a free port on the local machine?). I've also snoop:ed the network, and i can't see any milter-greylist "sync"-trafic. Has someone running Solaris noticed or fixed this problem for version 1.6rc1?
If so, please send a patch to Emmanuel Dreyfus...

I've noticed that most milter coding is done on BSD-systems.
But the company that i work for prefers Solaris :-(

TIA,
