Default OT: Problems sending emails to gmail. I used postfix debian install (based falko)

HI there,

Since we installed (or maybe gmail activated spam control) we have problems to send emails to gmail.com

Its a real problem or us because some customers use gmail accounts. I have setup SPF records, ptr, and so. so don't know what could be wrong . Of course, i'm sure we don't send spam!. the only difference between our installation server and falko howto, we added maia mailguard to server.

I post you the message when we send email to gmail (of course we tried to contact gmail, and it's imposible, they ghave an autoresponse support and that's all, we dont get reply from human):
