Hello llst,

I want to be able to log a message whenever control reaches a certain
point within a restriction class. Currently I have this:

smtpd_restriction_classes =
first_restriction,
second_restriction,
...

first_restriction =
check_client_access regexp:/etc/postfix/mesg-first-restriction
permit

/etc/postfix/mesg-short-greet-delay:

// WARN blah blah blah

This works, but it's pretty cumbersome. I've tried other approaches,
but they don't work:

first_restriction =
check_client_access static:WARN blah blah blah,
permit

Or even:

first_restriction_mesg = WARN blah blah blah
first_restriction =
check_client_access static:$first_restriction_mesg,
permit

Looks like the extra whitespace in first_restriction_mesg causes
problems for the parser.

Is there no easier way to log a message from within a restriction list?
