spaces when using "-o" in master.cf

[Tomas Macek]

I have line like this

smtpd_client_restrictions = check_policy_service inet:127.0.0.1:24575, ...

in my main.cf

I would like the $smtpd_client_restrictions to override in master.cf,
something like:

submission inet n - n - - smtpd
-o smtpd_client_restrictions=check_policy_service
inet:127.0.0.1:24575

but the space between "check_policy_service" and "inet" is a problem.

How can I write this (if it's possible generally)? I know, that the doc
says, the spaces are not allowed but maybe there is a way...

Regards, Tomas

Thanks, this seems to be also the solution.

But according to the http://marc.info/?l=postfix-users&m=108075412814545
(found after really long time) the "," (comma) did the job:

-o smtpd_client_restrictions=check_policy_service,inet:127.0.0.1:24575

How this can work?? :-o

You override by NOT including it in the "-o" list. Here you are
explicitly telling the submission service to execute this policy server.
Is this really what you want? Or are you trying to exclude this policy
server from submission? Note in my example there were BLANK lines after
"=" which excludes everything for the restriction class.

submission inet n - n - - smtpd
-o smtpd_client_restrictions=

means do not execute any client restrictions in the submission service.
Only list a restriction here if you DO want it to execute.

A comma is treated as whitespace by the postfix option parser. This
is a safe workaround for master.cf options. I'm certain this is
documented somewhere, but I don't see it right now...

If you have a long list of options, it's easier & cleaner to define
them in main.cf as suggested by Reindl, but either method is equally
valid.

-o smtpd_client_restrictions=$whatever_smtpd_client_restrictions

This is the recommended solution. It is mentioned in the master(5)
manpage, but the text is somewhat obscure. I have made the text
more explicit.

OLD: NOTE 1: do not specify whitespace around the "=". In
parameter values, either avoid whitespace altogether, use
commas instead of spaces, or consider overrides like "-o
name=$override_parameter" with $override_parameter set in
main.cf.

NEW: NOTE 1: do not specify whitespace around the "=" or in
parameter values. To specify a parameter value that con-
tains whitespace, use commas instead of spaces, or spec-
ify the value in main.cf. Example:

/etc/postfix/master.cf:
submission inet .... smtpd
-o smtpd_mumble=$submission_mumble

/etc/postfix/main.cf
submission_mumble = text with whitespace...

Postfix 2.9 and later will check that a user-defined $name in
master.cf has a definition in main.cf. It will log a warning if the
definition is missing (or mis-typed).

it's not "also". it's "the".

',' is a separator. so that works, but it is obscure. avoid it.
