Hi Olivier,

I used the following in Email_Local.pm. Maybe you can do something similar.

sub ParseCcAddressesFromHead {
    my %args = (
        Head        => undef,
        QueueObj    => undef,
        CurrentUser => undef,
        @_
    );

    my @recipients =
        map lc $_->address,
        map Email::Address->parse( $args{'Head'}->get( $_ ) ),
        qw(To Cc);

    my @res;
    foreach my $address ( @recipients ) {
        $address = $args{'CurrentUser'}->UserObj->CanonicalizeEmailAddress( $address );
        next if lc $args{'CurrentUser'}->EmailAddress   eq $address;
        next if lc $args{'QueueObj'}->CorrespondAddress eq $address;
        next if lc $args{'QueueObj'}->CommentAddress    eq $address;
        next if RT::EmailParser->IsRTAddress( $address );

        push @res, $address;
   }

    #
    # Limit the number of Cc addresses that we add to a
    # ticket during the initial create to minimize damage
    # to our Email reputation when SPAM slips through DSPAM.

    $RT::Logger->debug("$#res Ccs");
    if ( $#res > 3 ) {
        my @riceCc;
        my @nonriceCc;
        @riceCc = grep /rice.edu/i, @res;
        @nonriceCc = grep !/rice.edu/i, @res;
        $RT::Logger->debug("$#riceCc riceCcs, $#nonriceCc nonriceCcs");
        if ($#nonriceCc > 1) {
            @res = (@riceCc, @nonriceCc[0]);
        }
    }

    return @res;
}
