Hi Listusers

I have set up a hylafax mail-to-fax gateway and configured my postfix box so that I can send e-mails to 0123456789@xxxxxxxxxxxxxxxxxxxxxx and the mail text will be faxed to the fax number 0123456789.

Here's the configuration:

in /etc/postfix/master.cf I added following line:

fax       unix  -       n       n       -       1       pipe
    flags= user=fax argv=/usr/local/bin/faxmail -d -n ${user}

in /etc/postfix/transport I added the following:

fax.mybox.mydomain.tld   fax:localhost

In /etc/postfix/main.cf I added the following:

transport_maps = hash:/etc/postfix/transport
        fax_destination_recipient_limit = 1

Then I run

postmap /etc/postfix/transport

in order to update the transport database.

I can send faxes from mybox.mydomain.tld. However, when I send an e-mail from myotherbox.mydomain.tld, it bounces by saying that:

Nov 11 16:15:01 myotherbox postfix/smtp[6608]: E4D4731FB2:
  to=<0123456789@xxxxxxxxxxxxxxxxxxxxxx>, relay=none, delay=0,
  status=bounced (Name service error for name=fax.mybox.mydomain.tld
  type=A: Host not found)

My question: the postfix-hylafax documentation said that I should not advertise fax.mybox.mydomain.tld in the DNS. Is there a way to configure postfix so that remote MTAs won't bounce the mail? or do I have to put the virtual non existing local domain "fax" into the DNS?

Thanks a lot in advance

Mit freundlichen Grüssen - with kind regards - Meilleures salutations
