Running Behind Firewall

[edong]

Hi,

I'm running my ISPconfig server behind firewall, for two days it is running completely fine. but after subscribing to newsletter@ispconfig.org my ISPconfig server no longer receives mail. i tried to send mail from outside to my ISPconfig server but the mail bounces back and says:

Hi. This is the qmail-send program at someotherdomain.com.
I'm afraid I wasn't able to deliver your message to the following
addresses.
This is a permanent error; I've given up. Sorry it didn't work out.

<name@somedomain.com>:
x.x.x.x does not like recipient.
Remote host said: 554 <name@somedomain.com>: Relay access denied
Giving up on x.x.x.x.

SPAMASSASIN considered this as SPAM:

2.5 RCVD_IN_XBL RBL: Received via a relay in Spamhaus XBL

x.x.x.x is my firewall's IP
does my IP address is now listed in blocklist of spamhaus.org?
if so how can I unblock my IP address?
is there a way to add my firewall's IP to whitelist?
should i tweak my ISPConfig server to run behind firewall?

First of all, if your mailserver stopped working after you subscribed to the ISPConfig nwsletter it is a coincident. The newsletter subscription simply sends an email back where you have to click on the confirm link. You have posted this confirmation email from the newsletter subscription above.

To your spamhaus.org listing: Is your server hosted on a DSL line or in a datacenter? Most DSL IP addresses are listed at spamhaus.org and you cannot remove them from there because thy belong to the range of IP's that are listed for dynamic IP assignement (Dialup or DSL).
