Topic: iRedAPD-3.1 (Postfix policy server) has been released

Dear all,

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
