Topic: iRedAPD-3.1 (Postfix policy server) has been released
iRedAPD-3.1 (Postfix policy server) has been released, it fixes few issues, including one critical issue which causes email rejection on busy server. All users should upgrade as soon as possible.
Fixed: Not correctly set timeout of DNS query.
Default timeout of DNS query was too long (20 seconds), if the query took long time to get an answer, Postfix may reject emails and raise error: `warning: connect to 127.0.0.1:7777: Connection timed out`.
Plugin `greylisting` doesn't work if sender address is empty.
Upgrading is easy, just follow our short tutorial: https://docs.iredmail.org/upgrade.iredapd.html
