DNS service records not created even though mailbox folders are there

[dtargett]

DNS srv records are not being created by the symbiosis-dns-generate command, the template suggests these are created at the presence of a mailbox folder:

%if domain.respond_to?(:mailboxes) and domain.mailboxes.length > 0
#
# SRV records for various mail services
#
:_submission._tcp.<%= domain %>:33:<%= domain.srv_record_for(0,5,587, "mail."+domain) %>:<%= ttl %>
:_imap._tcp.<%= domain %>:33:<%= domain.srv_record_for(0,5,143, "mail."+domain) %>:<%= ttl %>
:_imaps._tcp.<%= domain %>:33:<%= domain.srv_record_for(0,5,993, "mail."+domain) %>:<%= ttl %>
:_pop3._tcp.<%= domain %>:33:<%= domain.srv_record_for(10,5,110, "mail."+domain) %>:<%= ttl %>
:_pop3s._tcp.<%= domain %>:33:<%= domain.srv_record_for(10,5,995, "mail."+domain) %>:<%= ttl %>

% end

These service records are not created. could this be removed from the template?
