Hi everybody,
First of all, thanks for trying to help. I still don't have a clue of what is going on, but one of the 3 servers that was bloking us is letting us pass now.
For you to have some extra info, I can send you the header of a bounced mail and the "reason" for it was bounced.

What is bugging me is that it just started without any strange change in the server (just changed the server for a virtual one with a more up to date MS and spf in spamassasin) and a DNS record so I can do round robin between 2 of my public ips (to have link failure tolerance) and it seems to be fixing on its own.<BR>
I also want to understand if I have something missconfigured in my gateway and that's why it validated recipients that don't exist in the mail server.<BR>
Regards,<BR>
<BR>
PS: I have tones of errors in my dns log trying to reach spamhaus and other blacklist providers:<BR>

<BR>
As well as many other fqdn (I think that it might be due to the server is trying send a reply to the forged senders).<BR>
Thanks a lot to everyone.<BR>
