Hi, normally greylisting should whitelist the senders IP after the next retry which is later than two minutes than the first try, at least in my case because GREYLISTING_BLOCK_EXPIRE is set to 2.

This has worked fine, but now it's not, at least in this example. I guess it works for other senders, because otherwise I would'nt recieve any other mails I guess.

Any Idea how to debug that? I can send uncensored log via private mail, but I don't wanna share this information with everyone smile

Re: Greylisting doesn't whitelist after later retries

- Which iRedAPD release are you running? Please show us output of command "ls -dl /opt/iredapd". If not the latest iRedAPD-3.3, please upgrade to 3.3 first and try again.
FYI: https://docs.iredmail.org/upgrade.iredapd.html

- If iRedAPD-3.3 has same issue, please turn on debug mode in iRedAPD and show us full log of related smtp sessions.
FYI: https://docs.iredmail.org/debug.iredapd.html

Note: please also pay attention to the sender server IP address, it may change for same email and this causes incorrect recognization.

It doesn't work.
I've sent uncensored logs to you via E-Mail.
