Hi Cesare !

You ask a goodf question, but unfortunately we cannot add a checkbox in
the Web GUI for every bit and blob option that a SMTP server or Qemu knows.
If we do this, we satisfy the power users, at the expense of getting 80%
of the users confused by having even more options for simple tasks

It is much better to propose sane defaults in the UI which cover most of
the use case, and leave the extra bits to manual editing of the
configuration files.
postfix is a depency of pve-manager, so all proxmox hosts have it
installed. So instead of fiddling with SSL expiration date in
pve-manager, it is much better to delegate the handling of this to postfix.

Now going back to the situation of having the SMP relayhost outside from
the LAN, I see at least two ways of setting that up:

* you can configure the relayhost, to only relay mail coming from your
LAN external IP adress

* as an extra step you can also configure postfix on the proxmox host to
send email via SSL and Authentification to your relayhost, there is a
good howto on that here, using Google SMTP servers as the relayhost but
it should work with any mail server.
