I am running a web-cyradm setup;
I have already some postifix checks in place to prevent it to be an open mail relay.
Unfortunately I recently had a problem since someone abused a mail form on the webserver running on the same host thus allowed to relay.
Apart from rewriting the mail form script to prevent this, what I would really like is postfix to check if the enveloper sender from one of my domains really exists.
e.g. if a mail pretends to be from " [EMAIL PROTECTED]", but "someone" is not an existing account, the mail should be rejected.
I know it can be spoofed, but I need it only for localhost (webserver) generated email.
I only found how to do it with postfix access tables, is there a way to do it also with web-cyradm mysql lookup?
Thanks in advance,
Lorenzo
