[Tech] Aiuto su configurazione server Postfix

[Artini Alessio]

Sto cercando di mettere in piedi un server con
Postfix+amavis-new+clamav+spamassassin.

Vorrei che il sistema funzionasse così:
1) tutte le e-mail che riceve siano ridirezionate
   verso un altro server.
2) per tutte le e-mail in ingresso deve essere
   fatto un controllo antispam e antivirus.
3) Attraverso un server web ho un sistema di newsletter
   (in html) che per ogni invio spedisca dal server i
   messaggi agli iscritti idem per squirrelmail.

Per provare utilizzo dalla shell della macchina il comando
Sendmail e mi si presentano una serie di problemi:

1) comando: sendmail -bm e-mail@NonApparetenteAlMioDominio 

Il sistema mi restituisce il seguente errore

sendmail postfix/smtp[20475]: 869A894426: to=<a.artini@inwind.it>,

Non voglio che il sistema faccia il controllo dell'esistenza
degli utenti e vorrei anche che le configurazioni per lo spam
vengano prese da un'unica locazione.
Perché mi da errore 550?

Anche in questo caso non voglio che il sistema faccia il 
controllo dell'esistenza degli utenti e vorrei anche che 
le configurazioni per lo spam vengano prese da un'unica
locazione.

Ecco alcuni parametri del mio main.cf:

mynetworks = 213.225.215.144/28, 127.0.0.0/8
myhostname = sendmail.comune.pontassieve.fi.it
mydomain = comune.pontassieve.fi.it
myorigin = $mydomain
mydestination = $myhostname, localhost.$mydomain, localhost, $mydomain
local_recipient_maps=
relay_domains = comune.pontassieve.fi.it
smtpd_recipient_restrictions = permit_mynetworks,
  reject_non_fqdn_sender,
  reject_unknown_recipient_domain,
  reject_unauth_pipelining,
  reject_non_fqdn_recipient,
  reject_unauth_destination,
  permit
relayhost = firewall.comune.pontassieve.fi.it:25



Grazie
