Re: [cobalt-users] Mail Server Overload Problems

["Hong Gao Qiang" <gqhong@xxxxxxxxxxxx>]

I don't have a SPAM filter installed when that happened.
The only thing I was using was the reject email address but then.... from my
case, SPAM filters may be useless as the emails are rebounded emails from
the main Mailer-Daemon of the other server. ( a few thousand a minute....)
And by the time I could block the email... the Process of my RaQ550 when
from 1.0 ro 20.0 and then it logged out.....

Because SPAM filers don't usually do blocking of these kind of "error"
messages.... our server was taken out before I could even do a thing.....
Now I use the SPAM filters, PO and MX records from my ISP and if there is a
flood, the only thing that gets jammed is my CatchALL account that is not
physically in the server :) Does not solves the problem but at least my
servers are not taken out :P\
