Close, but a CC_CLEAN may be set (and usually is) even for mail
with other ccats turned on. You should be checking explicitly for
undesired contents categories. For example:

  my $unwanted = $msginfo->setting_by_contents_category(
                   {CC_SPAMMY,1, CC_SPAM,1, CC_BANNED,1, CC_VIRUS,1} );
  if ($unwanted && $msginfo->msg_size < 1024*1024 ) { ...

Btw, the CC_* constants need to be imported from Amavis::Conf,
or their full name given, when using them in Amavis::Custom.
See below.

The @snmp_id may be left empty or unspecified.
The call in the example should be alright.


package Amavis::Custom;
BEGIN {
  import Amavis::Conf qw(:platform :confvars c cr ca);
  import Amavis::Util qw(do_log untaint min max);
}
sub new {
  my($class,$conn,$msginfo) = @_;
  bless {}, $class;
}
sub before_send {
  my($self,$conn,$msginfo) = @_;
  my $unwanted = $msginfo->setting_by_contents_category(
                   {CC_SPAMMY,1, CC_SPAM,1, CC_BANNED,1, CC_VIRUS,1} );
  if ($unwanted && $msginfo->msg_size < 1024*1024) {
    Amavis::do_quarantine($conn,$msginfo, undef,
      ['archive-quarantine'], 'sql:');
  }
}


Don't know what you mean by 'if it is an attachment'.
To detect attachments you'd need to traverse the MIME tree,
rooted at $msginfo->parts_root, or if you prefer the
MIME-Tools object: $msginfo->mime_entity.
