i installed iRedMail-0.7.4.stable on ubuntu11.10 64 bit

i did what you said. But i can sent 6 mails concurrently.

Please also make sure you don't have other restrictions apply on your testing email. For example, there's no quota limit based on SenderIP which will match your client IP address.

is there a solution ?

Thank you,   after I went through this problem I was awared of a thing that I need to add policy members my domain.
it works now. But I still have a problem.

I can manage to run throttling.
But I can't do "defer operation"
I use http://serverip/cluebringer and quotas tab
if I select DEFER to delay for mails exceeded the limit at the verdict.
postfix rejects mails exceeded my limit
Namely cluebringer behaves as reject about that.

How can I fix the issue ?

to test I sent an email towards 4 mail addresses as concurrently and I limit 2 concurrent as outbound mail.
I selected DEFER for limit exceeed at the cluebringer.
But the mail server REJECTED a mail due to exceeding limit

i wrote to them. one of them recommends me to use the last version of cluebringer (cluebringer-snapshot-2.1.x-201205100639).
he wants me to test with the last cluebringer .
Meanwhile, I can run cluebringer. it works as general. But when I select DEFER for limit exceeded outgoing mails . the postfix rejects exceeded mails.
But if select HOLD  postfix does right and it holds those mails.

How can I upgrade the last cluebringer or How can I reinstall cluebringer ?

Thanks

I downloaded it.
How can I upgrade to the latest sanpshot until the developers release a patch about that ?
Thanks
