No

See

To resume, if you want know if the external mail feature is enabled for a domain

Perl

if($data->{'EXTERNAL_MAIL'} eq 'on') {
# Do something when external mail feature is enabled
}

Code

package Listener::Named::OverrideDefaultMXRecords;
use strict;

'afterNamedAddDmnDb',
sub {
my ($wrkFile, $data) = @_;
if ( $data->{'EXTERNAL_MAIL'} eq 'on' ) {
# Remove default mailservers records
$$wrkFile =~ s/^(?:\@(?:\s+\d+)?\s+IN\s+MX|[0-9]\s+IN)\s+[^\n]+\n//gm;
# Add out-of-zone mailservers
$$wrkFile .= "$data->{'DOMAIN_NAME'}.\tIN\tMX\t$_.\n" for @mailservers;
0;
}
}
);
