Actually that's not the case. The callback is done with MAIL FROM:<>

I do that. A call forward to the next server in the chain to verify the
recipient before accepting the mail from the sender. I use Exim though.
It even caches the recipient verification results to avoid unnecesary
traffic. I don't know if it is that easy with postfix, but surely it is
doable.

Well yes. Maybe I oversimplified. What I do is a callback to the MX of
the envelope sender to see if it accepts mail to him/her. If not, the
mail is rejected with an explicative 550.

Well yes. Maybe I oversimplified. What I do is a callback to the MX of
the envelope sender to see if it accepts mail to him/her. If not, the
mail is rejected with an explicative 550.

o so.
Thanks for the compliment. In fact, blocking mail which cannot be
answered blocks a lot of forged sender spam too, something like 80%
here, being conservative.

s a bounce with a 550 explaining that
their ISP is blocking legitimate email from us. A lot of customers are
not even aware of the fact that their ISP is blocking legitimate email
at their backs. I have been able to white list my server in a number
servers without moving a finger, just angry users calling customer
service.

I use qmail, and the other big problem with it is, AFAIK, that it
accepts a message before checking if it has to be bounced. With forged
return email addresses one get a lot of bounced bounces. Very annoying.

I use qmail, and the other big problem with it is, AFAIK, that it
accepts a message before checking if it has to be bounced. With forged
return email addresses one get a lot of bounced bounces. Very
side, it could be a hardware problem too, memory being the
principal suspect.

20 is blocked, the
server times out trying to connect.
With passive mode turned off, it is your ftp client which actively tries
to establish a data connection, maybe through another port.
Take a look at your firewall settings in case it is you who is blocking
port 20, if not, it is your ISP.

otherwise ipmasq will wipe them every time the connection is restarted.
A big plus is that ipmasq sanitizes the firewall with default
security rules, such as filtering packets comming through an external
interface with an "internal" source address, and things like that.

I cannot agree more. It exists some kind of worldwide spam
psicosis and a tendency to cure the headache with the decapitation method.
