postfix 2.96 smtpd_relay_restrictions vs smtpd_reciepient_restrictions

Question

we are setting up postfix.main.cf and if use

smtpd_**relay**_restrictions = permit_mynetworks permit_sasl_authenticated reject_unauth_destination

we get the warning of

unused paramters

when we 'service postfix restart

if we comment out that line and instead use

smtpd_**recipient**_restrictions = permit_mynetworks permit_sasl_authenticated reject_unauth_destination

we dont get warning however this command is only supposed to work on much earlier versions of postfix (prior to 2.1). and also on the early version we maybe should use check_relay_domains instead of reject_unauth_destination??? maybe?

The only thing we can think of that somewhere other than postfix.main.cf there is the line smtpd_recipient_restrictions but we cannot find this.

help appreciated

Solution

You seem to be confusing version numbers.

If you run this command, you’ll see that you’re not running Version 2.10, which is the first version that supports smtpd_relay_restrictions.

postconf mail_version

Ubuntu precise (12.04) has postfix version 2.9.6, which supports what you want to do with the smtpd_recipient_restrictions parameter.

See http://www.postfix.org/postconf.5.html#smtpd_recipient_restrictions
