cannot run postfix with spamassassin

well, i think i can at least make things work once for a time:

in the file /etc/amavis/conf.d/05-domain_id it says:

Code:

chomp($mydomain = `head -n 1 /etc/mailname`);

# amavisd-new needs to know which email domains are to be considered local
# to the administrative domain.  Only emails to "local" domains are subject
# to certain functionality, such as the addition of spam tags.
#
# Default local domains to $mydomain and all subdomains.  Remember to
# override or redefine this if $mydomain is changed later in the config
# sequence.

#@local_domains_acl = ( ".$mydomain" );
@local_domains_acl = ( ".myfit.org" );

1;  # ensure a defined return

/etc/mailname contains: fmail.myfit.org

it seems that the chomp($mydomain = `head -n 1 /etc/mailname`); doesn't work properly?

i uncommented the default @local_domain_acl and replace with my manually added ".myfit.org" then the X-Spam tag appears in my header (of course i have to set $sa_tag_level_deflt to undef)

but does it means SA can only put its eyes on domains (what it means 'local domain') maintained by my email server? what if i have more than one-- or a list of - virtual domains? and if the server works as a relay server, so SA will have nothing to do with the emails going thru it?

anybody helps me out?
