I have the upgrade done following http://www.iredmail.org/docs/upgrade.iredapd.html
However the instructions for some of the new things don't tell how to do it
It's recommended to enable plugin reject_null_sender in iRedAPD-1.4.4 or newer releases to prevent authenticated user sending spam as null sender.
Where do it update Reject_null_sender to be a plugin?
In
Since version 1.4.4, iRedAPD supports Postfix smtp protocol state END-OF-MESSAGE, so you can enable iRedAPD in Postfix parameter smtpd_end_of_data_restrictions like below:
smtpd_end_of_data_restrictions = check_policy_service inet:127.0.0.1:7777, ...
Currently, only plugin amavisd_message_size_limit works in END-OF-MESSAGE state, other plugins work in RCPT state.
How do enable that? in postfix main it already has "smtpd_end_of_data_restrictions = check_policy_service inet:127.0.0.1:10031"
