Sender throttling is configured in /etc/policyd_sender_throttle.conf.

Re: Can't receive big mail

Delay is caused by greylisting, you can disable greylisting in /etc/policyd.conf for testing. Reference:
http://iredmail.org/wiki/index.php?titl … reylisting

It's recommended to enable greylisting.

Re: Can't receive big mail

It might be caused by Policyd.

- Did you enable sender throttling with Policyd? Could you please post output of command 'postconf -n' to help troubleshoot?
- If you have sender throttling enabled, please show us Policyd settings.

Re: Can't receive big mail

Did you try to disable Policyd in Postfix then test it again?

To disable Policyd in Postfix, simply remove 'check_policy_service inet:127.0.0.1:7777, ' in smtpd_recipient_restrictions.

WARNING: If you want to enable Policyd again, please make sure you add above restriction in the original order in smtpd_recipient_restrictions.
