Same for me, I have an ipfire as a firewall proxy server with a virtual environment behind it containing, among other things, a DNS, a mail server. for my mail server, I do not have any prb to send mail to other domains, however to receive them same observation, reception is impossible. The dmz or port forwarding functions of the internet-box are not advanced enough to implement double nating rules. the passthrou would be a big plus.
