(1) To use -o smtpd_client_restrictions in master.cf for the submission
port, I have been using
main.cf:
submission_client_restrictions = ...
master.cf
submission ... -o smtpd_client_restrictions =
$submission_client_restrictions
This seems to be necessary because of the space in "reject_rbl_client RBL".
This has been working in postfix 2.11 as far as I know. I recently tried
it with postfix 2.6 (the version provided by Amazon Linux, sigh) and it
doesn't seem to be working, though the problem may be something else (it
isn't an identical config).
Were user-defined parameters supported back in 2.6? (I notice postconf
-C doesn't exist in 2.6)
(2) I am considering whether to build postfix 3.2 from source on Amazon
Linux. If I bother, I want it to use a modern openssl (1.0.2k) built
from source. I would appreciate it if someone would explain how to
specify to the build where to find openssl (it would install in
/usr/local/ssl/{bin,lib}).
(3) Other suggestions welcome.
