I am new to Postfix. Sorry :(

This is a hosting server and I am having problems with only some users sending email and only from what appears to be certain ISPs. The one I'm working on at the moment is rr.com

First, I can set up an email account for this same user and send just fine. I am not on rr.com. It looks like maybe I'm having the same issue with myvzw.com.

You can see that I am also running amavisd-new. I do have a subscription to Spamhaus, but am not pulling in the PBL data.

From my logs, I get this (with only the actual domains changed to protect the innocent)

Nov 11 13:49:11 orion postfix/smtpd[7737]: NOQUEUE: reject: RCPT from rrcs-96-11-199-15.central.biz.rr.com[96.11.199.15]: 554 5.7.1 <webmas...@ew3d.com>: Relay access denied; from=<i...@example.com> to=<webmas...@ew3d.com> proto=ESMTP helo=<PCName>

I have checked that this IP address is not listed on any blacklist.

Here's my conf.

Thanks for any help!
