I have just realised that one of my server was OPENRELAY, according to http://vsmtp.pagasa.net/ and SpamHaus where I am blacklisted.
I cannot understand how this is possible since I followed Lotus recommendation strictly.
see “How to prevent Domino from being Used as a relay host”

Any help appreciated !!
Thanks in advance.

Check your firewall to make sure it is not the culprit. I have seen this happen before where the firewall is a trusted host and that is where the relay problem lies.

Well, my firewall is a hardware device (ZyWALL 10W ).
I have no idea to where to look.
Tanks for the adice. I’ll ask my vendor.
