[bug] Add smtpd_relay_restrictions to postfix conf
smtpd_relay_restrictions was added in postfix 2.10 (jessie
has 2.11 atm). Without this, outbound mails are rejected to
be relayed.
from http://www.postfix.org/SMTPD_ACCESS_README.html:
NOTE: Postfix versions before 2.10 did not have
smtpd_relay_restrictions. They combined the mail relay and spam blocking
policies, under smtpd_recipient_restrictions. This could lead to
unexpected results. For example, a permissive spam blocking policy could
unexpectedly result in a permissive mail relay policy. An example of
this is documented under "Dangerous use of
smtpd_recipient_restrictions".
smtpd_relay_restrictions defaults to
'permit_mynetworks, permit_sasl_authenticated, defer_unauth_destination'
and is configured here to check for a valid client cert.
see http://www.postfix.org/postconf.5.html#smtpd_relay_restrictions
- Resolves: #7856
