[Comphelp] Spam filter?

[Jim Williams]

ISPs occasionally block mail from specific IP addresses or servers that 
they think might be involved in SPAM or have an open relay.  Usually, the 
mail is blocked in error and a call to the ISP (yours if you are not 
receiving mail) will resolve the problem.  I subscribe to 4 USPS e-mail 
lists.  I was receiving mail from all of them but the IP address used to 
send rosters was blocked by my ISP.  A call resolved the problem, but I 
think ISPs are getting a little cavalier in the way they block messages 
since most of the blocks seem to be without just cause.
