Okay, the webserver is a Plesk server where users can set an email redirection
to their external address. I don't
know why, but many users do that.
i am out here because i never use such software using server
configuartions natevily all of the time and if need/usefull
develop my own webinterfaces
As I cannot handle these sender rules on every single one Plesk I have (qmail
or postfix...), I have to set up a
mail gateway for outgoing mails. I also have Bluequartz working with sendmail,
and Kerio servers, working with
custom MTAs.
thats the problem with PLESK and "ready" software
in my setups i can enforce psotfix configurations on one
central mysql-database and every single relay on any
webserver is using this tables as need readonly for
enforcing rules
So, as I understood, correct me if I'm wrong, my email gateway does only see an
email going from [email protected] to
[email protected], none of which are in my local domains.
in your case it may be difficult
in my setup it is easy
* user has a sender-adress to type we are owning, ever
* any host is checking for alloweed senders
* forwarding are only done on the gateway
so the gateway doe snever see any foreign sender for outigoing messages
Okay I ask myself something now...
In my case I cannot discard all unwanted mails, but perhaps can I detect
when there are more than 10 messages / minute (for example) from a
single not-local domain? That would dramatically decrease the number of
outgoing spams from my infrastructure.
I don't know if I can do that with postfix...
