Hi, I have a postfix installation and it accepts all email to specified domains regardless of the user part. This seems to pose a security hole in sending spam / viruses.
Say someone sends an email to the server with the from of
"[EMAIL PROTECTED]" and the to of "[EMAIL PROTECTED]",
postfix accepts this email although there is not local account for
[EMAIL PROTECTED] It then tries to bounce the message back
including the full message and any attachments.
Postfix is configured with virtual domains retrieved from an sql
database.
Can anyone point me in the right direction for getting postfix to reject
messages for non-existent local accounts instead of just bouncing it?
Thanks and best wishes,
Shri
