Difference between the pass and unix types in master.cf

chaouche yacine
Hello list,

man 5 master says that :


<<<unix   The service listens on a UNIX-domain socket and is acces-
sible for local clients only.>>>

[...]


<<<pass   The service listens  on  a  UNIX-domain  socket,  and  is
accessible  to  local  clients only. **It receives one open
connection  (file  descriptor  passing)  per   connection
request.**>>>

What does the part between "**" add or remove from a classic unix socket ?

Postscreen uses this feature to send the file handle for an
open connection to an smtpd process.
