Ok I will show you an example. I think its very important to
understand both MTAs to decide what´s really better in what situation
but this is another story.

Here is an example of the access file.

192.168.0 RELAY
127.0.0.1 RELAY
From:[EMAIL PROTECTED]   550 Spam denied
From:[EMAIL PROTECTED]             550 SPAM F*CK YOU SH*T SPAMMER
From:[EMAIL PROTECTED]         550 SPAMMER BUY YOURSELF
From:[EMAIL PROTECTED]     550 LOAN YOURSELF, SPAMMER
From:[EMAIL PROTECTED]     550 F*** YOU SPAMMER
oo.net                          550 SPAAAAMMMEERRRR

It looks like as if this file is similar as the rpcthosts (?) file on
qmail, but its not the same. I relay incoming mails from my 192.168.0
class c network as well as localhost mails.

But if there is coming a mail from "from:..." the mail will be
rejected, and if there is a hostname only, the complete host is denied
to send us any mails.

This file has nothing to do with outgoing mails.

I use this file to setup a mini-light spamfilter and to setup general
relaying rules. Fetchmail delivers the mail to sendmail (at the moment
to qmail, hahah) so the relaying is allowed. I think its very easy to
setup and very easy to handle.

Is there a qmail thingy to do the same?

Ok. Thanks.

There is a perl module somewhere I have seen on the qmail page I think
I will try this first.

Thanks for you answers, they helped me a lot. The next step is to find
out how are virtual users working (users without system accounts).

After that I think I have completed this part.

Qmail is nice, but sendmail is not bad at all i was using sendmail a
long time without any problems.

Sometimes I think the qmail-people think that sendmail is an enemy to
qmail, but I can´t understand this.
