[exchange 2000] Block spam address

Hi All,



I have some addresses that receive spam every day, all the messages come 
from the same sender so I want to block the sender. I could do this on the 
client side but then an other user can get the messages so I would like to 
block the sender on the server side.



I was wondering how to do that. I have searched on TechNet but the most 
there is about exchange 2003.



Maybe you could help me, hope so !

Go into Exchange system manager, then global settings, right click on message 
delivery and choose properties, then click on the Sender Filtering tab. In 
there you can define sender filters either explicitly or by wildcard. 

Another more comprehensive spam blocking method is to use RBL's. On the 
Connection filtering tab, add in RBL service providers like dnsbl.sorbs.net 
or sbl-xbl.spamhaus.org. This will block known spam senders regardless of the 
sender. 

IMPORTANT:
After you setup filtering, goto Administrative Groups, your AG, your server, 
protocols, SMTP, then right click on the SMTP virtual server and goto 
properties. In there click on the advanced button and select the filter 
mechanisms you want to enable on incoming SMTP traffic.

I did as you told. i.e. I have added dnsbl.sorbs.net in DNS suffix of
connection filter.
And enabled connetion filter in the smtp server advances properties.

thing is under advance property, I have only one record " All
unassigned" , TCP Port 25 with filter enabled. is it okay ? or IP
address should be selected ? IF yes, I have 2 IPs ( 1 internal &
anothor external ) which one I should select ?

And also tell me.. can we have more than one filter. like
1.dnssbl.sorbs.net
2.sbl.spamhaus.org 
3.spews.relays.osirusoft.com

please help

Exchange 2003 SP2 + Security Updates = OWA Problems
Hi guys! I wonder if anyone can shed any light on why whenever I install the latest patches on my Exchange 2003 server, the OWA stops working and users receive a: SERVICE NOT WORKING message when going to the web page. Add/Remove programs and uninstall the latest security updates and it works again. Is this a common problem? Does anyone have any fixes? I don't want to put on SP2 until I work out why it is doing it. Cheers in advance for any help. Andy On Mon, 28 Nov 2005 08:11:07 -0800, "Andy" <Andy@discussions.microsoft.com> wrote: >Hi guys! > >I w...

Exchange 2003 mailbox permissions being reset
I have seen many posts on this same problem with no real answer, hopefully somebody out there has found a solution. I add "send as" rights to a mailbox for a user other than the owner of the mailbox (or full access, make no difference) and it works fine for a short while, then when less than an hour goes by (not sure exactly how long), the user that was added in the permissions tab is missing and obviously the send as ability is gone. I have tried adding the user on the Security tab, then also hitting the advanced button and adding it there (per ms kB#327000). The user that I'...

Exchange 5.5 intrasite replication through a firewall
Hi there, I am hoping someone can help, I have looked all over forums and found what I thought would be the solution but is does not work. I have a mixed mode Exchange site with 3 Exchange 2003 servers (SP2 running on w2k3 sp1) and one Exchange 5.5 server (sp4 & post sp4 rollup running on w2k sp4). The 5.5 server is in a DMZ so I have attempted so set static ports for the DS, IS MTA and SA, but in reality all I really need is the DS as this is not a mailbox server, simply an OWA server for the other sites that are still running on Exchange 5.5.

address lists or public folders?
Hi all, I am a newbie to Exchange. I am currently evaluating and testing Exchange 2003 for our office. I would like to know what is the recommended way of maintaining public & private contacts lists. What I would like to do is as follows:- 1. Maintain a public list of employees and their email addresses. 2. Allow each employee to also setup their own private list of Contacts and giving them the ability to only allow certain other users (maybe secretrary) have visibility. This way they can get access to their Contacts remotely too i.e. via OWA or via Pocket PC hot sync? So which is bette...

From a Temp Exchange 2003 to a new Production one
Hi Thanks for taking the time to read this. I recently migrated an Exchange 5.5 system to a new Windows 2003 Forest with Exchange 2003. All went very smoothly (Phew!) The Exchange 5.5 system ran (until yesterday) on a decent server. The Exchange 2003 system is running on a temporary server at the moment. Having decommissioned the Old Exchange 5.5 server now, I've rebuilt it as a Windows 2003 server in the new domain and have installed Exchange 2003 upon in. It has appeared as a new server within the organisation. Excellent so far. What I want to do is move all mailboxes, public f...
