The default amavisd.conf configuration contains a @blacklist_sender_maps configuration that matches some special senders such as “optin at something” and directly blocks the email regardless of score.

Subject: Re: Email quarantined with low score
Thanks Dominic,
My spamassassin and amavis are vanilla except for 50-user which looks like
:~$ cat /etc/amavis/conf.d/50-user
use strict;
#
# Place your configuration directives here. They will override those in
# earlier files.
#
# See /usr/share/doc/amavisd-new/ for documentation and examples of
# the directives you can use in this file
#
$max_servers = 4;
@local_domains_acl = ( ".$mydomain" );
$ENV{PATH} = $path = '/usr/sbin:/sbin:/usr/bin:/bin<sbin://sbin:/usr/bin:/bin>';
$enable_dkim_verification = 1;
@whitelist_sender_acl = @local_domains_acl;
$final_virus_destiny = D_DISCARD; # (defaults to D_BOUNCE)
$final_banned_destiny = D_DISCARD; # (defaults to D_BOUNCE)
$final_spam_destiny = D_DISCARD; # (defaults to D_REJECT)
$final_bad_header_destiny = D_PASS; # (defaults to D_PASS), D_BOUNCE suggested
$virus_admin = "virusalert\@$mydomain";
$spam_admin = "postmaster\@$mydomain";
#------------ Do not modify anything below this line -------------
1; # ensure a defined return
So im a bit surprised it can end up quarantined with a lower score than required, any help on where else to look or how to understand this is appreciated.

Perhaps the report you are seeing which reads 'Spam detection software, running on the system "acmewebsites", has NOT identified this incoming email as spam' was generated by Spamassassin (or another spam detection software), not by Amavis. Amavis takes the total score given by the other spam detection software (usually Spamassassin) and can then adjust it according to more rules of its own before making a final decision. Amavis's rules might even bypass all previous scoring and impose an automatic discard. They are described in files in /etc/amavis/conf.d, especially 50-user.
