Re: Is Postfix Checking Spamhaus RBL

the email originated from in my Thunderbird mail client. From that IP it was transfered via SMTP [25] to 64.38.48.101 and that IP is 'vss155.webhosting-email.com. I hope that was a bit more clear than my 1st ramble... Ah, maybe they're looking at all the headers, which is really stupid! -- Ralf

Re: Is Postfix Checking Spamhaus RBL

I ask what the normal procedure is for mail? If the latter IP is listed on a PBL but the last received IP is not, does it then allow? Does Postfix only look at the the most recent received client IP for RBL checks and thats all? Of course. Everything else cannot be trusted anyway. -- Ralf
