I am running it on W2K Advanced server (we are doing load balancing for failover) although it will run nicely on W2K Server (what we initially tested it on) uses its own SMTP server .. can run on the machine that Exchange is on or another one ... we run it as a service ... our path looks something like this Xwall ---> Exchange (Front end servers) (separate servers) If you want more detailed info, feel free to contact me directly ...

I was just taking a look at Xwall and it does in fact look pretty good. Questions: What operating system are you running it on? Does it need a separate SMTP server to be running or does it provide its own? If it needs another, what do you suggest?

We have used Xwall for about a year. It is very good. It is one guy I think. He is very responsive. It seems like when you ask if something can be done, it gets put in the next release ... I think he is Austrian , so be a little careful with his choice of good/bad english words ... We use Bayesian filtering on it. I would suggest that you first get your other filters in place and are happy with them before you start collecting stats to start your bayesian filtering. Then, once it is working, review the emails and the stats (in .csv files) and set your level a touch higher than what you think it should be ... You can also edit the NDR's ... Does virus scanning ... Etc, etc, etc, you name it ... I also took the .csv's and the collected the blocked messages and made an .asp site for my users, so that they could log in through a web page and "unblock" email addresses (it also does "unique" whitelists for individual users ...) For the price, it is great ... Probably be bought out soon ... mike -----Original Message----- From: Alverson, Tom [mailto:[EMAIL PROTECTED] Sent: Thursday, October 30, 2003 9:53 AM To: Exchange Discussions Cc: '[EMAIL PROTECTED]' Subject: RE: Off-topic changing SMTP port on Exchange for spam filtering. Let us all know what you think of Xwall if you get it running. I looked at their web page and it's only $350 per server (any number of users). If it works that sound very reasonable.

Exchange 5.5 Sorry if this came through twice. Had to change the text type and re-send. This is a little off-topic. We are about to deploy XWall for Exchange on our front end IMC relays. One of the requirements is that we change the smtp port for Exchange on the IMC's to use 24 since XWall will use port 25 and get the messages first. I guess my questions are: For users using POP or custom applications that are using the Exchange IMC as their relay host, how will changing the ports affect them? Have I just disabled POP by installing XWall? We have locked down all unused ports so I guess I need to open port 24 up to the front end and back end servers as well. Is there anything I need to be careful about or any other gotchas that I should know. _________________________________________________________________ List posting FAQ: http://www.swinc.com/resource/exch_faq.htm Web Interface: http://intm-dl.sparklist.com/cgi-bin/lyris.pl?enter=exchange&text_mode=&; lang=english To unsubscribe: mailto:[EMAIL PROTECTED] Exchange List admin: [EMAIL PROTECTED] _________________________________________________________________ List posting FAQ: http://www.swinc.com/resource/exch_faq.htm Web Interface: http://intm-dl.sparklist.com/cgi-bin/lyris.pl?enter=exchange&text_mode=&; lang=english To unsubscribe: mailto:[EMAIL PROTECTED] Exchange List admin: [EMAIL PROTECTED] _________________________________________________________________ List posting FAQ: http://www.swinc.com/resource/exch_faq.htm Web Interface: http://intm-dl.sparklist.com/cgi-bin/lyris.pl?enter=exchange&text_mode=&; lang=english To unsubscribe: mailto:[EMAIL PROTECTED] Exchange List admin: [EMAIL PROTECTED] _________________________________________________________________ List posting FAQ: http://www.swinc.com/resource/exch_faq.htm Web Interface: http://intm-dl.sparklist.com/cgi-bin/lyris.pl?enter=exchange&text_mode=&lang=english To unsubscribe: mailto:[EMAIL PROTECTED] Exchange List admin: [EMAIL PROTECTED] _________________________________________________________________ List posting FAQ: http://www.swinc.com/resource/exch_faq.htm Web Interface: http://intm-dl.sparklist.com/cgi-bin/lyris.pl?enter=exchange&text_mode=&lang=english To unsubscribe: mailto:[EMAIL PROTECTED] Exchange List admin: [EMAIL PROTECTED]
