It was manufactured by a company called Whistle that was later acquired by IBM. Since the acquisition, IBM released a second Interjet and then one year later discontinued the product and support. We're having difficulty with an open relay on the e-mail server and mail is being rejected by several recipients to avoid spamming. I'm unable to find a setting on the Interjet that might close the relay. We are providing NAT and DHCP services from the e-mail server, but it is unclear how this would cause an open relay. Do you have any suggestions for resolving this issue short of replacing the e-mail server? If replacement is the only solution, can you suggest a server that is as simple to operate and maintain as an appliance such as the Interjet. - Via the Internet I did some checking and Interjet seems to be a product IBM wants to forget. I wasn't able to find any technical information on the product anywhere on the site. Replacement isn't the first option I would look at. First, consider putting in an e-mail proxy server. This would be something for those on the outside to try to spam through and could serve as a platform to reduce the amount of spam coming into your company. By taking a look at <http://www.spamassassin.org/> (recently made part of the Apache Software Foundation), you will find several documents that walk you through setting up Spam Assassin as a tool to reduce the amount of spam coming into your company without having to figure out all the settings on your own. If you don't want to set up your own system, you will also find links on this site third-party solutions that come in an appliance form ready to stick in the rack and get to work. If neither of these options work for you, one of the simpler mail servers I have set up recently is Novell's NetMail 3.5 ( <http://www.novell.com/products/netmail/> ), which can run on a variety of platforms. You don't have to have a Novell server running in order to use this, and the management tools couldn't be simpler. If you're looking for a more Linux-oriented solution ( <http://www.nwfusion.com/topics/linux.html> ), you can also get NetMail on this platform or you can go with a more Linux-conventional approach by using something like Sendmail ( <http://www.sendmail.org/> ) or Postfix ( <http://www.postfix.org/> ) to handle the mail. Although either Sendmail or Postfix can be a little intimidating to configure, if you add something such as Webmin ( <http://www.webmin.com/> ) as a management front end, you a more a point-and-click approach instead of digging through multiple layers of configuration files. I don't think providing NAT and DHCP could be the cause of your open relay. See if there is a configuration option that requires you to authenticate before being able to send mail. Although this would require you to make a minor change on all workstations, it should help address the open relay problem. Without knowing how your Interjet appliance is wired into the network, it might be possible to introduce a small hardware-type firewall that provides NAT and DHCP functionality. You could then turn off those features on Interjet and see if the problem continues. _______________________________________________________________ To contact: Ron Nutter Ron Nutter, a Master Certified Novell Engineer and Microsoft Certified Systems Engineer in the Lexington, Ky., area, tracks down the answers to your questions.
