:-) Nice to meet you, I was no more expecting to have a reply.

Yep, apart that about 1000 km... it would be annoying to make some
disaster, the main task of that system ends out with sending mail.

send-mail: /etc/smail/config: unknown attribute: smtp_remote_allow
Alas I fear that the version string "Smail-3.2 1996-Jul-4 #2" means
_before_ that feature was added, sendmail does not work any more, the
above line is what I got when I tried to send out mail as a user of the
box.
I have ftp'ed the smail docs and man pages from that 1.3.1 box and have
just started reading (I've also looked for the attribute smtp_remote_allow
with no success so far). See attachment: tried a quick test with no
results, I mean smail was still working but still acting as an open email
relay. I'll have to read more... well I could also look for an old smail
package, just less old than the one running there, enough to support the
attribute you suggested but not enough to be incompatible with libraries
on Debian 1.3.1, will give a look at the Debian site...(?)

Yes, ciao Martin and _thanks_ a lot again (these nights are going to
finish soon I hope, looking forward to have that problem fixed and the
laptop used by Linux at its best possibilities, I think we don't have the
APM and modem drivers yet, a pity, windog's telnet is a disaster with
emacs... why does it work with pico/pine instead?).
Pant, going to sleep, "tomorrow" will be short damn :-(
