remove spam before forwarding
Hi all,
I have a postfix with a couple of virtual hosts and a /etc/postfix/virtual
file with my users
.
some users prefer that mail from my postfix server mail.domain1.com gets
forwarded to an exchange server at mail.domain2.com
Now all users have a .procmailrc file in their home directory that moves al
tagged spam to /dev/null But users who also forward mail to domain2 still
get the full load of spam traffic to domain2.
How can I remove all incoming spam directely instead of first processing it
via procmail, so domain2 doesn't get all the spam traffic that arrived first
at domain2?
Biggest problem atm is that I see that all the spam traffic that gets
forwarded create too many connections and so things get into a loop...

Thanks for the suggestion Dan but it's just for a couple of accounts, most
accounts don't use or need forwarding.
Is there any other way to move all incoming spam directely to /dev/null
Now I have a .procmailrc in each $HOME with the following
MAILDIR=$HOME/Mail
LOGFILE=$HOME/Mail/log
:0:
* ^X-Spam-Status: Yes
But this only deletes it locally, so the spam is not deleted if it's being
forwarded to another email address

Use a product designed for a forwarding MTA like amavisd-new. It will
quarantine the spam and viruses and forward on all of the ham.

one approach would be to use header_checks in the "after the filter"
postfix (you need a specific cleanup service)
/^X-Spam-Flag: Yes/ HOLD
This applies to _all_ mail.
Using amavisd-new is a better approach.
This is a question for the postfix-users list, so followups there please.
