Dear confocal listserv members--

There apparently are computers making brute-force and dictionary attacks 
on accounts with popular e-mail servers such as yahoo.com and gmail.com. 
  Once compromised, the account is used to send spam--sometimes to 
everyone on the victim's address list.  The recipients could include 
this listserv.

To help avoid problems, please take a moment to consider the strength of 
the password you use on your account.  The guidelines are simple: use no 
words or names from any language; longer is (exponentially) better; mix 
uppercase, lowercase, numerical and symbolic characters.  Of the above, 
probably the most important are to avoid words and names, and to 
increase length.  A 6-character password can be cracked in seconds; a 
14-character password could take years by the same machine.  Wikipedia 
has a discussion of password strength if you're interested.

Thanks and secure computing!

Martin Wessendorf
