mindsuck asks: "As of this Wednesday, my ISP blocked my port 25, leaving my mailserver useless to the outside world as a consequence of spammers and their nasty worms. So I decided to ask the nice people of Slashdot. What can I do now to restore my smtp service, besides changing ISPs, is there a obscure way to run a mailserver off a non-standard port? What about services similar to those provided by dyndns.org for this kind of situations? Pros and Cons of using this services? Should I move my MX to a more 'stable' server than my homegrown one?" This topic was last touched upon in this article, from 2002. It's been over a year since SMTP blocks have become commonplace. Have you noticed a slowdown in your SPAM? Are ISP SMTP blocks really helping the problem? Updated: It looks like Charter is also blocking SMTP. Might there be a way to work with your ISP to get them to unblock port 25 for you, if you can sufficiently satisfy them that you are not a spammer?

Von-at-Infosec_Writers asks: "It is relatively easy to trace a hack back to a particular computer, but proving that a specific person committed the crime could become much more difficult especially since, as a recent CNN.com article stated, a hacker's legal defense can be: it wasn't me but my hijacked computer that committed the crime. 'In some cases, I do suspect there are people whose computer is taken over by third parties. It's also a clever defense to exculpate your client,' says Michael Allison of the Internet Crimes Group.What are possibilities to overcome this problem; to prove that the computer owner, without a doubt, is in fact responsible or not responsible for the crime?" As computers become more and more prevalent in our infrastructure, the consequences for computer crime become that much more serious. How much responsibility does the owner of an Internet-connected computer have for crimes committed using their equipment, and what are ways we can best determine their involvement, or lack of it, in said crimes?

Futurepower(R) asks: "Microsoft Windows 2000 and Windows XP have crippled file systems. The file system cannot copy some of the files that are necessary to the operating system. If you don't have experience with Microsoft operating systems, you may find this amazing, but it is true; Microsoft supplies no method of backing up and restoring fully operational copies of Windows 2000 and Windows XP. Microsoft's advice is to reinstall the operating system and all programs every time you want to move to a new or backup computer. For confirmation of this, see the 'Microsoft Policy Statement' in the article, The Microsoft Policy Concerning Disk Duplication of Windows XP Installations. Many industries use numerous programs; installing them all may take a week or even more. All of the disk image duplication programs I've used have problems, in my experience. What program do you use? What has been your experience with it? Can you recommend a program, or recommend staying away from one?"
