Med senare versioner av sendmail måste man vilka domäner som den
accepterar att vidarebefordra. Definiera dina domäner med classen R
eller i filen /etc/mail/relay-domains.

| ANTI-SPAM CONFIGURATION CONTROL |
+---------------------------------+
The primary anti-spam features available in sendmail are:
* Relaying is denied by default.
* Better checking on sender information.
* Access database.
* Header checks.
Relaying (transmission of messages from a site outside your domain to
another site outside your domain) is denied by default. Note that
this changed in sendmail 8.9; previous versions allowed relaying by
default. If you want to revert to the old behaviour, you will need
to use FEATURE(`promiscuous_relay'). You can allow certain domains to
relay through your server by adding their domain name or IP address to
class 'R' ($=R) using RELAY_DOMAIN() and RELAY_DOMAIN_FILE() or via the
access database (described below).
If you use
FEATURE(`relay_entire_domain')
then any host in any of your local domains (that is, the $=m class)
will be relayed (that is, you will accept mail either to or from any
host in your domain).
...
confCR_FILE FR class [/etc/mail/relay-domains] Name of
file used to get the local additions
to the $=R (hosts allowed to relay)
class.
...
CLASSES
...
R domains we are willing to relay (pass anti-spam filters)

Sedan bör du se till att den sändande maskinen har en
'fully qualified domain name', dvs. att den finns med i DNS.
Sedan säger du i ditt mail att du har en smtpserver (som inte är samma
maskin). Om du har all mail på mailservern kan du väl använda FEATURE:
nullclient This is a special case -- it creates a stripped down
configuration file containing nothing but support for
forwarding all mail to a central hub via a local
SMTP-based network. The argument is the name of that
hub.
Eller om du är ute efter en nullclient, kolla in:
$ apt-cache show ssmtp
