Please disregard this post. Issue was firewall configuration, not zimbra.
Basically I have a business dsl connection for my servers and comcast for the family. Everything works great except when sending mail to other comcast.net users. I get the following error:
"Mail to Comcast is rejected and is returned with an error message containing the code BL001. What does this mean?
You have been blocked from emailing the Comcast network because we have determined that you are sending email from a dynamic/residential IP address within the Comcast domain. Comcast does not allow subscribers to send email from a mail server other than smtp.comcast.net. "
Specifically I wanna change this:
"Received: from zimbra.mydomain.com (COMCAST_IP.hsd1.or.comcast.net [MY_COMCAST_IP])
by mx.google.com with ESMTP id 3si4839125rvi.14.2008.03.29.12.20.07;
Sat, 29 Mar 2008 12:20:08 -0700 (PDT)"
I would like to make it so when a computer sends mail from my Comcast connection that it appears as if it was sent from the Zimbra box. I've tried using the Zimbra webui and it still originates from my comcast ip.
Also, I tried forwarding all SMTP and SMTP/S traffic from the lan directly over the dsl connection via pfsense firewall rule but that didn't fix anything either.
Thanks in advance!
