[SATLUG] Fwd: Undelivered Mail Returned to Sender

[Herb]

Gee Bob since you are an expert in this area maybe you can explain (not 
solve) my problem so I can understand ... I have a hosted website and so 
from that site I can and do receive any mail sent to @lookcee.com but 
3weeks ago I began getting thousands per day of bounced mail that has 
random ###@ so it all flows into my box when it is bounced from the addy 
to: filter. I am not smart enough to know how to write a script to stop 
this and am waiting for the webmaster to fix it.

So my question is why can anyone send spam out and if the TO:addy 
refuses to receive it returning the mail how can they simply route it to 
me..I fully agree that the mail system is damn sure broken since just in 
receiving this huge volume into my box it fills my web capacity and and 
I don't know what all happens but I do know I cannot even save any mail 
up to the server archive. just today I have dled headers and deleted 
over 6,000 pieces of mail, you can imagine how slow that is on a 40kbps 
dialup.
