Re: [Asrg] Measurements on spam

Hi,

In my experience, with spam arriving to a single domain. 
They do 
arrive in surges and last for few minutes/hours depending on
the spammer,
but generally they occur close to each other. It depends on
the spam list 
being used.

The domain in question ayna.com receives over 400k messages
a day, and most 
of it is spam.  And regardless of what filters are
installed, junk will go
through it.  Many times it bottles up and no mail gets
through until the
spammer attacks slow down. 

As a mail provider I am more inclined to use stamps as a way
to filter out 
spam.  If the spammer wants to get to the network and pays,
that is fine with 
me, as long as I recoup the cost of running the server.

thanks
Adonis
