Resolved Problem with SPAM RBL zen.spanhaus.org ?

[Alain Ronce]

Server operating system version

Debian 10.12

Plesk version and microupdate number

18.0.46

Hello,
I am using the black list setup with zen.spanhaus.org for all my domains, but all the mail to the server are rejected with :
"554 5.7.1 Service unavailable; Client host [**.**.***.***] blocked using zen.spanhaus.org; v=spf1 a -all\r\n"
The IP of the host is not blacklisted.
Does anyone have an idea concerning what could happen?
Best Regards
AR

I think you have a better chance for it to work if you fix the typo (it's spamhaus).

Oh ! I'm so sorry, what a stupid error! I have to go to an ophthalmologist
Thank you for your answer.

Dont use zen list... as many real clients on dynamic ips by their provider will get blocked. At least that happens in my country.

Exactly as intended. Users on dynamic IP should never send mail directly & unauthenticated.
They should only send mail through their mail provider after authentication.
Blocklists are bypassed for authenticated users.
