Problem with sendmail and spamhaus

Hi,

I added the line below to my sendmail.mc and then regenerated the
sendmail.cf file.

FEATURE(`dnsbl', `sbl-xbl.spamhaus.org', `"550 5.7.1 ACCESS DENIED to
<"$&f"> thru "$&{client_name}" by The Spamhaus SBL+XBL DNSBL ; Please visit
http://www.spamhaus.org/ for more information."')dnl

It's working fine by stopping spams from spamhaus list before mails could
even reach mailscanner and thus freeing my server load. I love this feature
a lot as we are getting tons of spams daily.

But the problem is, some of my users also are unable to send their emails
using SMTP server as their "dynamic" IP is banned because some of the ips
are listed in spamhaus. They keep getting the error above. How can I
rectify this? Is there a command for me to add to allow user based on their
IP address or email address?

Perhaps I could allow IP address of certain range (within my ISP) to go
through this? After all, once the mails pass through this barrier, there
are also Mailscanner to take care of the spams.

Thanks in advance.
