We have had the technology to do digitally signed authentication for many 
years and yet still companies and people do not sign their email and look 
what happens

and I mean REAL signatures not just what the congress thinks is digitally 
signed material.

Shes of the Emulex Corporation plunged more than 60 percent Friday 
following the distribution of a bogus press release about the computer 
network equipment maker's earnings.

Trading in the stock was halted for about three hours after the hoax 
started showing up in financial news reports. The hoax wiped more than $2 
billion off the company's stock market value, leaving it around $2 billion.

Emulex's shares finally resumed trading at 1:30 p.m. Eastern time and 
recaptured most of their loss. The stock was lately trading down 6, or 5.3 
percent, at 107 1/16 after earlier plunging as low as 43.

The fake press release, which appeared on the Internet around the time of 
the market's opening bell, claimed that Emulex would restate it fiscal 
fourth-quarter earnings as a loss. There were also headlines that the 
Securities and Exchange Commission was investigating accounting 
irregularities at the company and that Emulex's president and chief 
executive, Paul Folino, was stepping down.
