Email Address Verification - .Net - The Real Way!
Every so often a useful component emerges from various companies programming in ASP and ASP.Net. Recently, I needed to validate legitimate email addresses; but not lexically. That is, I did not want to merely test if there was as @ symbol in the address; rather, I wanted to see if the email address actually existed or if it was rejected.

How your Firewall Caused a Mess!
Firewalls are types of hardware or software applications that block vulnerabilties and hackers from gaining access to your network or to your user desktop. The adage, "You can't have your cake and eat it too", seems to be underlined in today's news article.
ISS, or Internet Security Systems, has a major flaw in their software firewall called Black Ice. A worm discovered by a hacker "...generates a random IP address and sends itself via UDP to a random destination port. After 20,000 attempts, it writes 65K of data to the local disk(s). It then rinses and repeats, ad nauseum. Because the cycle is so brief, a great deal of damage can be done before an infected machine exhibits signs of corruption. Re-booting will eliminate the worm, but the system may already be damaged enough to fail. "
Nice to know your firewall on your desktop; your anti-hacker toolkit, has caused a hole large enough to destory the data you are trying to protect. If you own any of the following versions; protect yourself by downloading the patches from ISS:
BlackICE Agent for Server 3.6 ebz, ecd, ece, ecf
BlackICE PC Protection 3.6 cbz, ccd, ccf
BlackICE Server Protection 3.6 cbz, ccd, ccf
RealSecure Network 7.0, XPU 22.4 and 22.10
RealSecure Server Sensor 7.0 XPU 22.4 and 22.10
RealSecure Desktop 7.0 ebf, ebj, ebk, ebl
RealSecure Desktop 3.6 ebz, ecd, ece, ecf
RealSecure Guard 3.6 ebz, ecd, ece, ecf
RealSecure Sentry 3.6 ebz, ecd, ece, ecf

Noticable Problems w/Outlook 2003 and IMAP
Dana has noticed the same as we have here at rjsNetworks. The IMAP protocol built into Outlook 2003 is very slow and often unresponsive. According to Microsoft, this is due to 'network latency'. Well; we are on the same network, with a 100 Mbit link to our mail servers, we still notice that the protocal is has poor performance when compared with Thunderbird or Microsoft's own Outlook Express. Just proves that free can supercede things you pay for.
