netstat output & postfix

[Matteo Cavalleri <shivabrahma_(_at_)_tiscali_(_dot_)_it>]

on openbsd 3.3 (with a custom kernel with no ipv6)  a simple "netstat
-a" listed me all active sockets on my system. now on openbsd 3.5 and a
generic kernel "netstat -a" shows just ipv6 sockets. BUT if i do a
"netstat -f inet" i see some ipv4 sockets but not all. for example i
don't see any socket open on port 25 even if i've postfix running...

why does it happen? the man page says nothing useful to me, and a search
on the mailing list archive didn't find anything...

question 2: i'm configuring postfix to do relay for clients inside the
lan and to do relay for "external" clients only if they auth themselves
(with sasl 2). are there common or not so common errors i should look
for? i've read different tutorials and my config should be
ok, but since i'm not doing exactly what the tutorial says i'd like to
test postfix before putting an open relay on the internet...

question 3: i'm going to configure postfix with tls to have an ecrypted
smtp session when i connect from outside. i'd like to do the same with
the pop3 protocol. afaik popa3d just understand cleartext password over
cleartext session, so i'll need to use another pop3 daemon. which is
your preferred tls pop3 server under openbsd?


thanks in advance
