Postfix-Djigzo Communication

Zitat von Manuel Faux <Manuel.Faux(a)>:

I don't want to change any configuration, I only referenced the
default configuration described in the installation guide and used
in the appliance. Postfix is told by content_filter =
djigzo: to queue mails through which
is James. The string "djigzo" represents the transport defined in

djigzo unix - - n - 4
  -o smtp_send_xforward_command=yes
  -o disable_dns_lookups=yes
  -o smtp_generic_maps=

This is the UNIX socket I've referenced. What does is do?

This is a "clone" of smtp (sending) with special override parameters
(-o ...) and in this case the "unix" is for communication with the
Postfix master process and qmgr/cleanup, not for the sending part
which is TCP/IP for "smtp" client.
