Topic: Recipient address rejected: Intentional policy rejection, please try

==== REQUIRED BASIC INFO OF YOUR IREDMAIL SERVER ====
iRedMail    1.6.1
iRedAdmin-Pro    5.4 (MySQL)

====


Good morning,
I have a problem with a certain sender.
Some of the e-mail accounts on my server receive e-mail from him, but others do not and receive the message "Recipient address rejected: Intentional policy rejection, please try again later"

I know this is caused by the greylist filter, but I would not like to whitelist this domain.
I know how greylist works, but I wonder how it is configured in iredadmin.
In my opinion, the sender is rejected in the first phase, and only when he repeats the same message within a strictly defined time is he allowed by the server.
In my case, this does not happen (perhaps because the ovh server re-sends each time from a different IP?) -logs

Additionally, if such a message is allowed, is the sender's email address/server/domain permanently saved somewhere, or is a greylist search carried out every time an email is sent?

Re: Recipient address rejected: Intentional policy rejection, please try

As you can see, sender server retried with different servers (check the "helo=<...>"), hence all retries are unique and it will never bypass greylisting.

In this case you can whitelist sender domain for greylisting service. Manage this in iRedAdmin-Pro: System -> Greylisting, input "@ases.pl" in section "Do not apply greylisting on listed senders".

greylisting causing more problems than solving them, so it's better to have it turned off.

Adding to the greylist solved the problem
